Chemical Structure
Description
(E)-2-methoxy-4-((4-oxo-3-(1-phenylethyl)-2-thioxothiazolidin-5-ylidene)methyl)phenyl 4-nitrobenzoate (C26H20N2O6S2) contains a steroid 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.
