Chemical Structure
Description
1-(4-Chlorophenyl)-N-(4-methoxyphenyl)-5-methyl-1H-1,2,4-triazole-3-carboxamide (C17H15ClN4O2) contains a steroid core, an amide 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.
