And the article was included in Journal of Macromolecular Science in 2013.Name: 4,6-Dichloro-N-phenyl-1,3,5-triazin-2-amine The following contents are mentioned in the article:
Two novel 1,2-3,4-bridged and 1,3-bridged calix[4]arenes and based on large s-triazine conjugate systems were designed and synthesized in high yields. The liquid-liquid extraction experiment showed that they possessed excellent extraction abilities towards one cationic and three anionic dyes [Orange I (OI), Methylene blue (MB), Neutral red (NR), Brilliant green (BG)]. The highest extraction percentage of compound was 91.2% for BG. The complexation UV-visible spectra of compounds and with four dyes indicated the existence of complexation action between hosts and guests with 1:1 ratio of complexation in DMSO solution The association constants suggested that the 1,2-3,4-bridging structure was more favorable for producing excellent complexation abilities than 1,3-bridging structure. The association constant of compound with BG was ≤4.5 × 106 M-1. This study involved multiple reactions and reactants, such as 4,6-Dichloro-N-phenyl-1,3,5-triazin-2-amine (cas: 2272-40-4Name: 4,6-Dichloro-N-phenyl-1,3,5-triazin-2-amine).
4,6-Dichloro-N-phenyl-1,3,5-triazin-2-amine (cas: 2272-40-4) belongs to organic chlorides. Chlorinated organic compounds are found in nearly every class of biomolecules and natural products including alkaloids, terpenes, amino acids, flavonoids, steroids, and fatty acids. Alkyl chlorides are versatile building blocks in organic chemistry. While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available.Name: 4,6-Dichloro-N-phenyl-1,3,5-triazin-2-amine
