Chemical Structure
Description
(3R,6S,8aS)-6-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-5-oxohexahydro-5H-thiazolo[3,2-a]pyridine-3-carboxylic acid (C23H22N2O5S) contains a flavonoid core, an amide group, a sulfone 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.
