Reference of (1S,2R)-1-Amino-2,3-dihydro-1H-inden-2-ol. The article was titled 《Facile Access to Optically Active 2,6-Dialkyl-1,5-Diazacyclooctanes》. The information in the text is summarized as follows:

Herein, the 1,5-diazacyclooctane (1,5-DACO) bearing a chiral auxiliary obtained from the formal [4+4] cycloaddition of N-alkyl-α,β-unsaturated imines was reported. 1,5-DACO could be further derivatized by nucleophilic alkylation to give various chiral substituted 1,5-DACO derivatives I [R = Me, vinyl, Ph, etc.]. The removal of the chiral auxiliary was effectively carried out using hydrogenation over Pearlman’s catalyst. This methodol. allows the production of a broad range of unprecedented optically active 2,6-dialkyl-1,5-DACO II, which could not be accessed by other methods. In the part of experimental materials, we found many familiar compounds, such as (1S,2R)-1-Amino-2,3-dihydro-1H-inden-2-ol(cas: 126456-43-7Reference of (1S,2R)-1-Amino-2,3-dihydro-1H-inden-2-ol)

(1S,2R)-1-Amino-2,3-dihydro-1H-inden-2-ol(cas: 126456-43-7) belongs to anime. Amines characteristically form salts with acids; a hydrogen ion, H+, adds to the nitrogen. With the strong mineral acids (e.g., H2SO4, HNO3, and HCl), the reaction is vigorous. Salt formation is instantly reversed by strong bases such as NaOH. Neutral electrophiles (compounds attracted to regions of negative charge) also react with amines; alkyl halides (R′X) and analogous alkylating agents are important examples of electrophilic reagents.Reference of (1S,2R)-1-Amino-2,3-dihydro-1H-inden-2-ol

The author of 《Molecular capture using the precipitate of creaming-down by (-)-epigallocatechin-3-O-gallate》 were Tsutsumi, Hiroyuki; Sato, Ayano; Fujino, Satoru; Fujioka, Yusuke; Ishizu, Takashi. And the article was published in Chemical & Pharmaceutical Bulletin in 2019. Recommanded Product: 3-Pyridinemethanol The author mentioned the following in the article:

An aqueous solution of equimol. amounts of 2-chloropyrimidine and (-)-epigallocatechin 3-O-gallate (EGCg) afforded a colorless block crystal, which was determined to be a 2 : 2 complex of 2-chloropyrimidine and EGCg by X-ray crystallog. anal. The 2 : 2 complex was formed by the cooperative effect of three intermol. interactions, π-π and CH-π interactions, and intermol. hydrogen bonds. Upon formation of the 2 : 2 complex, a 2-chloropyrimidine mol. was captured by a hydrophobic space formed by the three aromatic rings of A, B, and B’ rings of two EGCg mols. The mol. capture abilities of various heterocyclic compounds using EGCg were evaluated by ratio of the heterocyclic compounds included in the precipitates of complex of EGCg to the heterocyclic compounds used. The amount of the heterocyclic compounds was measured by an integrated value of corresponding proton signals in the quant. 1H-NMR spectrum. The results came from multiple reactions, including the reaction of 3-Pyridinemethanol(cas: 100-55-0Recommanded Product: 3-Pyridinemethanol)

3-Pyridinemethanol(cas: 100-55-0) belongs to pyridine. Pyridine is very deactivated towards electrophilic substitution with respect to benzene. For this reason classical formylation, using methods such as the Gattermann or Vilsmeier reactions, are not generally successful. Recommanded Product: 3-Pyridinemethanol

The author of 《Functionalized Anion-Exchange Membranes Facilitate Electrodialysis of Citrate and Phosphate from Model Dairy Wastewater》 were Paltrinieri, Laura; Huerta, Elisa; Puts, Theo; van Baak, Willem; Verver, Albert B.; Sudhoelter, Ernst J. R.; de Smet, Louis C. P. M.. And the article was published in Environmental Science & Technology in 2019. Safety of 3-Aminopropan-1-ol The author mentioned the following in the article:

Here, the preparation of a new, functional anion-exchange membrane (AEM), containing guanidinium groups as the anion-exchanging sites (Gu-100), is described as well as the membrane characterization by XPS, water uptake, permselectivities, and elec. resistances. The functional membrane was also used in pH-dependent electrodialysis experiments using model dairy wastewater streams. The properties of the new membrane are compared to those of a com. available anion-exchange membrane bearing conventional quaternary ammonium groups (Gu-0). Guanidinium was chosen for its specific binding properties toward oxyanions: e.g., phosphate. This functional moiety was covalently coupled to an acrylate monomer via a facile two-step synthesis to yield bulk-modified membranes upon polymerization Significant differences were observed in the electrodialysis experiments for Gu-0 and Gu-100 at pH 7, showing an enhanced phosphate and citrate transport for Gu-100 in comparison to Gu-0. At pH 10 the difference is much more pronounced: for Gu-0 membranes almost no phosphate and citrate transport could be detected, while the Gu-100 membranes transported both ions significantly. We conclude that having guanidinium groups as anion-exchange sites improves the selectivity of AEMs. As the presented monomer synthesis strategy is modular, we consider the implementation of functional groups into a polymer-based membrane via the synthesis of tailor-made monomers as an important step toward selective ion transport, which is relevant for various fields, including water treatment processes and fuel cells.3-Aminopropan-1-ol(cas: 156-87-6Safety of 3-Aminopropan-1-ol) was used in this study.

3-Aminopropan-1-ol(cas: 156-87-6) belongs to anime. Many important products require amines as part of their syntheses.

The author of 《New polymeric adsorbent materials used for removal of phenolic derivatives from wastewaters》 were Davidescu, Corneliu-Mircea; Ardelean, Radu; Popa, Adriana. And the article was published in Pure and Applied Chemistry in 2019. Name: 3-Hydroxybenzaldehyde The author mentioned the following in the article:

For the treatment of waste waters containing phenols or phenolic compounds several unconventional methods are applied, such as: inverse osmosis, coagulation, solvent extraction, flotation-coagulation combined processes, adsorption, and anaerobic processes. From all used remediation processes adsorption has a higher applicability degree due to its main advantages: simplicity, ease of use and operation and high efficiency. It is important to develop and use new adsorbents with higher regeneration degree and longer life time. Chem. modification of polymeric matrixes with pendant functional groups is a valuable method used to improve the surface and interface chem. of polymeric adsorbents, to achieve better adsorption performance and to design tailor-made adsorbents with respect to specific pollutants. In present study new adsorbent materials were obtained starting from chloromethylated styrene-divinylbenzene copolymers with different degrees of crosslinking (6.7%, 12% and resp. 15% DVB), functionalized by reaction with 3-hydroxibenzaldehyde. The polymeric intermediates were further modified by polymer-analogous reaction with iso-propylamine and diethylphosphite with the aim to improve their adsorptive properties. The obtained polymeric adsorbents were tested for remediation of waters containing phenol (P), 2,3-dimethylphenol (2,3-DMP) and 2,4,6-trimethyl-phenol (2,4,6-TMP). Based on obtained exptl. data the adsorption mechanism, process kinetics and thermodn. were studied.3-Hydroxybenzaldehyde(cas: 100-83-4Name: 3-Hydroxybenzaldehyde) was used in this study.

The author of 《Direct growth of covalent organic framework nanofiltration membranes on modified porous substrates for dyes separation》 were Pan, Fusheng; Guo, Weixiong; Su, Yanlei; Khan, Niaz Ali; Yang, Hao; Jiang, Zhongyi. And the article was published in Separation and Purification Technology in 2019. Formula: C9H6O6 The author mentioned the following in the article:

Covalent organic frameworks (COFs) are emerging as crystalline porous materials for advanced membranes, due to their regular pore structures and high porosity. The fabrication of defect-free ultrathin COFs membranes is still very challenging, since the poor COF-substrate affinity hampers the nucleation of COF crystallites. In this work, a facile direct growth method was developed to deposit continuous imine-based COF layer (TpPa-1, synthesized by the Schiff-base reactions of 1,3,5-triformylphloroglucinol (Tp) with p-phenylenediamine (Pa-1)). Aldehydes groups were firstly immobilized on polyacrylonitrile (PAN) porous substrate as the nucleation sites to promote the growth of continuous TpPa-1 layer via a good COF-to-substrate adhesion. Fourier transform IR spectroscopy (FTIR), scanning electron microscope (SEM) and X-ray diffractometer (XRD) confirmed the formation of COF layer. The TpPa-1/HPAN membrane exhibited high water flux of 418.5 L/(m2 h MPa) under the operation pressure of 0.1 MPa and excellent dyes rejection (93.91% for Orange GII and over 99% for Methyl blue, Congo red and Alcian blue). The high separation performance, coupled with its facile fabrication and remarkable stability, may render imine-based COFs membrane promising for wastewater treatment. In the experimental materials used by the author, we found 2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde(cas: 34374-88-4Formula: C9H6O6)

The author of 《Reduction-responsive poly (ethylene glycol)-dexamethasone biarm conjugate and its self-assembled nanomicelles: Preparation, physicochemical characterization, and thiol-triggered drug release》 were Ngoc, Van Tran Thi; Hwang, Hee Sook; Kim, Yugyeong; Kang, Han Chang; Huh, Kang Moo. And the article was published in Polymers for Advanced Technologies in 2019. Formula: C3H9NO2 The author mentioned the following in the article:

In this study, a reduction-responsive poly (ethylene glycol)-dexamethasone biarm conjugate was synthesized as intracellular targeted drug delivery carriers. The hydroxyl end group of methoxy poly (ethylene glycol) (mPEG) was modified to introduce a biarm structure with bioreducible disulfide bond and amine end groups. Dexamethasone (Dex) as a nuclear targeting moiety was conjugated to the amine end groups of mPEG biarm derivatives, mPEG-(NH2)2 or mPEG-(ss-NH2)2, with or without bioreducible disulfide bonds. The bioreducible and nonreducible mPEG-Dex biarm conjugates, R-mPEG-Dex and N-mPEG-Dex, were synthesized and characterized by various anal. methods, proton NMR (1H-NMR), Fourier transform IR spectroscopy (FT-IR), dynamic light scattering (DLS), and fluorescence measurements. Amphiphilic mPEG-Dex conjugates self-assembled in aqueous solutions to form nanoparticles (NPs) with a size range of 130 to 150 nm, and their critical micelle concentrations (CMCs) were determined to be 12.4 and 15.3 mg/L, resp., for bioreducible and nonreducible ones. The R-mPEG-Dex NPs maintained good colloidal stability in the presence of bovine serum albumin (BSA) for more than 1 wk but demonstrated a significant change in colloidal stability in the presence of dithiothreitol (DTT). In DTT-containing phosphate-buffered saline (PBS), the bioreducible NPs showed not only reduction-responsive destabilization with PEG shedding but also thiol-dependent drug release profile. Our observations indicated that the R-mPEG-Dex NPs have a promising prospective as an efficient nanocarrier for intracellular targeted delivery of various anticancer drugs. In addition to this study using 2-Aminopropane-1,3-diol, there are many other studies that have used 2-Aminopropane-1,3-diol(cas: 534-03-2Formula: C3H9NO2) was used in this study.
