Chemical Structure
Description
2-((5-(4-Chlorophenyl)-4-(p-tolyl)-4H-1,2,4-triazol-3-yl)thio)-1-(3-methoxyphenyl)ethanone (C24H20ClN3O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
