The occurrence of N-(4-Chlorophenyl)-2-((4,5-diphenyl-4H-1,2,4-triazol-3-yl)thio)acetamide is closely related to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
N-(4-Chlorophenyl)-2-((4,5-diphenyl-4H-1,2,4-triazol-3-yl)thio)acetamide (CAS 328020-51-5), molecular formula C22H17ClN4OS and molecular weight 420.91 g/mol, is a CATO reference standard with documented purity and traceability.
N-(4-Chlorophenyl)-2-((4,5-diphenyl-4H-1,2,4-triazol-3-yl)thio)acetamide (C22H17ClN4OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; 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.
