Chemical Structure
Description
Ethyl 4,5-dimethyl-2-(2-((3-(m-tolyl)-1H-1,2,4-triazol-5-yl)thio)acetamido)thiophene-3-carboxylate (C20H22N4O3S2) 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.
