Reduction of nitro compounds, RNO2, by hydrogen or other reducing agents produces primary amines cleanly (i.e., without a mixture of products), but the method is mostly used for aromatic amines because of the limited availability of aliphatic nitro compounds. Reduction of nitriles and oximes (R2C=NOH) also yields primary amines.Quality Control of (1S,2R)-1-Amino-2,3-dihydro-1H-inden-2-ol

In 2019,Journal of the American Chemical Society included an article by Sasmal, Himadri Sekhar; Halder, Arjun; Kunjattu H, Shebeeb; Dey, Kaushik; Nadol, Athulya; Ajithkumar, Thalasseril G.; Ravindra Bedadur, Prachiti; Banerjee, Rahul. Name: 2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde. The article was titled 《Covalent Self-Assembly in Two Dimensions: Connecting Covalent Organic Framework Nanospheres into Crystalline and Porous Thin Films》. The information in the text is summarized as follows:

Insolubility of covalent organic frameworks (COFs) in organic solvents is one of the major obstacles for the potential application of these extended networks such as drug delivery, sensing, optoelectronics, and semiconductor device fabrication. The present work proposes a unique way to make uniform, solution-processable, crystalline, and porous COF nanospheres directly from the homogeneous solution of amine and aldehyde via spatial and temporal control of the nucleation and growth. This strategy of direct nucleation simultaneously showcases the caliber to tune the size of the COF nanospheres from 25 to 570 nm. We have also demonstrated the concept of mesoscale covalent self-assembly of those solution-processable COF nanospheres in the liquid-liquid interface (DCM-water bilayer) for the very first time, transmuting them into self-standing COF thin films with long-range ordered arrangements in two dimensions. The crystalline and porous (with TpAzo showing highest SBET of 1932 m2 g-1) free-standing COF thin films could be fabricated in a wide range of thicknesses from as low as 21 nm to as high as 630 nm. Both β-ketoenamine (TpAzo, TpDPP) and imine (TpOMeAzo, TpOMeDPP) linked COF thin films have been synthesized via mesoscale covalent self-assembly of the solution-processable COF nanospheres illustrating the generality of this eloquent methodol. Further, the solution processability has been tested and utilized to cast COF thin films uniformly in the inner and outer surface of an alumina hollow fiber membrane. The COF thin film-alumina hollow fiber membrane composites have showcased promising selective mol. separation of He and O2, He and CO2, and He and N2. The experimental process involved the reaction of 2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde(cas: 34374-88-4Name: 2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde)

Name: 3,5-Dihydroxybenzaldehyde The article mentions the following:

Breast cancer represents the most frequently diagnosed malignancy in women worldwide. Various therapeutics are currently used in order to halt the progression of breast tumor, even though certain side effects may limit the beneficial effects. In recent years, many efforts have been addressed to the usefulness of natural compounds as anticancer agents due to their low toxicity. Resveratrol, a stilbene found in grapes, berries, peanuts and soybeans, has raised a notable interest for its antioxidant, anti-inflammatory, and antitumor properties. Here, we report the design, the synthesis and the characterization of the anticancer activity of a small series of imino N-aryl-substituted compounds that are analogs of resveratrol. In particular, the most active compound, named 3, exhibited anti-tumor activity in diverse types of breast cancer cells through the inhibition of the human topoisomerase II and the induction of apoptotic cell death. Therefore, the abovementioned compound maybe considered as a promising agent in more comprehensive treatments of breast cancer.3,5-Dihydroxybenzaldehyde(cas: 26153-38-8Name: 3,5-Dihydroxybenzaldehyde) was used in this study.

Application of 6381-59-5 And the article was included in Industrial & Engineering Chemistry Research in 2020. The article conveys some information:

Two Et lactate (EL)-based aqueous two-phase systems (ATPSs) were studied at T = 298.15 K and atm. pressure. Sodium tartrate and potassium sodium tartrate organic salts have been used to form biphasic systems.

Binodal curves were fitted with the Merchuk equation obtaining a good fit. Moreover, modeling with the universal quasichem. thermodn. equation was carried out to accurately represent the two-biphasic systems. Furthermore, exptl. binodal curves obtained in this work and literature results for the same systems and for systems with EL and other salts were analyzed regarding their similarity. Finally, the application of the adopted ATPS in the partitioning of two flavonoids, rutin and quercetin, was studied in terms of the partition coefficients and the percentage of extraction Rutin and quercetin showed better affinity to the EL-rich phase, evidencing that the use of the proposed ATPS may be a successful technique in the biotechnol. industry for the separation of each flavonoid.
