The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: Silver(I) trifluoromethanesulfonate(SMILESS: O=S(C(F)(F)F)([O-])=O.[Ag+],cas:2923-28-6) is researched.HPLC of Formula: 1260667-65-9. The article 《Evaluation of halogen chain-end functionality in 2-bromo-2-methylpropanoate esters of poly(oxyalkylene) polymers by MALDI-TOF spectroscopy》 in relation to this compound, is published in Polymer Bulletin (Heidelberg, Germany). Let’s take a look at the latest research on this compound (cas:2923-28-6).
Esters of 2-bromo-2-methylpropanoate of poly(oxyalkylene) polymers such as poly(ethylene glycol) or α-Me poly(ethylene glycol) were prepared in high yields and characterized by spectroscopic and chromatog. methods (NMR, FT-IR, mass spectroscopy and SEC). The halogen chain-end group in the poly(oxyalkylene) bromine-terminated esters was characterized by MALDI-TOF MS. The effect of the solvents (methanol or tetrahydrofuran) and the cationic agents such as silver trifluoroacetate (AgTFA), silver trifluoromethanesulfonate (AgTFS) and sodium trifluoroacetate (NaTFA) on the mass spectra was studied. Anal. of the mass spectra demonstrated that the analyte was transformed to unsaturated (elimination), alkoxy or hydroxyl end-groups (substitution) mols. when silver cationic agents were used; these results were also supported by 1H NMR study. When sodium salt was used as a cationic agent, well-defined bromine-terminated macromols. were successfully determined through MALDI-TOF MS. Well-characterized esters of 2-bromo-2-methylpropanoate of poly(oxyalkylene) polymers could be used as ATRP macroinitiators for the synthesis of a variety of polymeric architectures of interest as drug delivery bioconjugates.
There is still a lot of research devoted to this compound(SMILES：O=S(C(F)(F)F)([O-])=O.[Ag+])Quality Control of Silver(I) trifluoromethanesulfonate, and with the development of science, more effects of this compound(2923-28-6) can be discovered.
