Chemical Structure
Description
Methyl (3S,4R)-1-benzyl-4-((tert-butoxycarbonyl)amino)pyrrolidine-3-carboxylate (C18H26N2O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
