Dai, Li; Lou, Jiangfei; Baek, Na-won; Zhang, Xun; Yuan, Jiugang; Xu, Jin; Fan, Xuerong published an article in 2022. The article was titled 《A rapid way of preparing switchable bacteria-killing and bacteria-releasing cellulosic material with anti-bacteria adhesion capability》, and you may find the article in Cellulose (Dordrecht, Netherlands).Application In Synthesis of 3-Bromopropan-1-ol The information in the text is summarized as follows:

At present, some multifunctional and smart materials equipped with both “”bacteria-killing”” and “”bacteria-defending”” functions have been created to meet the demands of some particular application areas. However, most of these materials were either biol. incompatible or required intricate crafting. In this paper, a finishing agent containing quaternary ammonium lactone ring and NCO groups was developed. Particularly, the quaternary ammonium lactone ring can transfer to zwitterionic form in alk. conditions, providing possibilities for switching of different functions. As a result, this agent was demonstrated to be quickly and covalently grafted to cellulosic materials. Moreover, the finished fabrics can kill more than 99.90% of bacteria (both E. coli and S. aureus) when they are in the form of quaternary ammonium lactone ring structure, and it can release almost 99.00% of the bacteria after being transferred to the zwitterionic form. Simultaneously, the zwitterionic state has a 99.90% efficiency of anti-bacteria adhesion. Hence, this is an easy and rapid way to realize the multifunction of “”bacteria-killing””, “”bacteria-releasing”” and “”anti-bacteria adhesion”” on cellulosic material. It has a great application prospect in inner single-use medical materials to kill the attached bacteria, further release them before using and prevent the materials from being attached by bacteria again. The experimental part of the paper was very detailed, including the reaction process of 3-Bromopropan-1-ol(cas: 627-18-9Application In Synthesis of 3-Bromopropan-1-ol)

A short sequence for the practical synthesis of polysubstituted unsym. 1,10-phenanthroline compounds was developed based on the palladium-catalyzed oxidative cross coupling reaction of C(sp2)-H/C(sp3)-H bonds of carboxamides. DMAP as a preferred ligand was crucial for the reaction to avoid β-hydride elimination, which may be controlled by the π-π stacking effect between the aryl group of the substrate and DMAP, demonstrated by primary mechanistic studies and X-ray data of the substrate-Pd-DMAP complex. In the experiment, the researchers used many compounds, for example, (1S,2R)-1-Amino-2,3-dihydro-1H-inden-2-ol(cas: 126456-43-7Recommanded Product: 126456-43-7)

And the article was published in ACS Applied Polymer Materials in 2019. Recommanded Product: 627-18-9 The author mentioned the following in the article:

Interest in plastic scintillators for the detection of special nuclear materials (SNMs) has increased in recent years due to the development of systems capable of distinguishing between neutron and γ radiation. For example, poly(vinyltoluene) (PVT)-based scintillators overdoped with the fluorescent small mol. 2,5-diphenyloxazole (PPO) distinguish the two types of radiation via pulse shape discrimination (PSD). However, PPO overdoping leads to softening of the plastic and dopant aggregation, causing major issues with detection efficiency, lifetime, and scalability. To improve the plastic scintillator properties while retaining efficient PSD performance, methacrylate-based derivatives of PPO were synthesized for copolymerization with vinyltoluene. The use of polymerizable dopants results in PSD capable plastic scintillators with increased mech. and thermal stability while eliminating dopant aggregation and leaching. The experimental process involved the reaction of 3-Bromopropan-1-ol(cas: 627-18-9Recommanded Product: 627-18-9)

And the article was published in Nippon Nogei Kagaku Kaishi in 1954. Reference of 4-Butylbenzene-1,2-diol The author mentioned the following in the article:

A com. product consisting of liver oils from cods and sharks containing about 36,000 international units of vitamin A/g. oil served as the substrate. The antioxidant activity was expressed by the stability (number of days required for 50% loss of vitamin A in the liver oil) and the inhibitor ratio defined as (Lx-Lc)/(Ls-Lc), where Lc is the stability of liver oil in the absence of antioxidant, Ls the stability of the oil treated with the standard antioxidant, IXa, Lx the stability of the oil treated with the test antioxidant. The inhibitor ratio for 0.05 and 0.10%, resp., was as follows: Et gallate, 0.70, 0.98; Et 4-(3,4-dihydroxyphenyl)butyrate, 0.63, 0.77; Me 6-(3,4-dihydroxyphenyl)hexanoate, 0.67, 0.77; [3,4-(HO)2C6H3]2(CH2)n (A) (n = 3), 0.83, 1.00; A (n = 4), 1.42, 1.40; A (n = 5), 1.17, 1.21; A (n = 6), 1.17, 1.21; A (n = 9), 0.88, 0.91; A (n = 10), 0.88, 1.00; II, 1.08, 1.12; VII, 1.08, 0.98; and III, 0.75, 0.81.4-Butylbenzene-1,2-diol(cas: 2525-05-5Reference of 4-Butylbenzene-1,2-diol) was used in this study.
