Li, Kaiqi; Liu, Xiliang; Chen, Long; Xiong, Zuochun; Xiong, Chengdong; Chen, Dongliang published an article in 2022. The article was titled 《Synthesis of new aliphatic poly(ester-carbonate)s bearing amino groups based on photolabile protecting group and evaluation of antibacterial property》, and you may find the article in Polymers for Advanced Technologies.Reference of 2-Aminopropane-1,3-diol The information in the text is summarized as follows:
Amino-functionalized six-membered cyclic carbonate 5-((2-nitrobenzyl) amino)-1,3-dioxan-2-one (NBAC) was synthesized with 2-nitrobenzyl group as photolabile protecting group. The following copolymerization was carried out by using L-lactide as comonomer and Sn (Oct)2 as catalyst. The amino-functionalized polymer P(LA-co-AC) was obtained by UV irradiation of P(LA-co-NBAC) to remove the protecting group. The structures of products were confirmed by 1H NMR and 13C NMR anal. The pendant amino groups not only resulted in an enhancement of the hydrophilicity, but also played a role of antibacterial effect due to the pos. charge imparted to the material. In the part of experimental materials, we found many familiar compounds, such as 2-Aminopropane-1,3-diol(cas: 534-03-2Reference of 2-Aminopropane-1,3-diol)
2-Aminopropane-1,3-diol(cas: 534-03-2) belongs to anime.Typically the presence of an amine functional group is deduced by a combination of techniques, including mass spectrometry as well as NMR and IR spectroscopies. 1H NMR signals for amines disappear upon treatment of the sample with D2O. In their infrared spectrum primary amines exhibit two N-H bands, whereas secondary amines exhibit only one.Reference of 2-Aminopropane-1,3-diol
