Chemical Structure

1-[(4-Chlorophenyl)methyl]-3-methyl-4-[4-(propan-2-yl)phenyl]-4,5-dihydro-1H-1,2,4-triazol-5-one CAS 860785-29-1 chemical structure

Description

1-[(4-Chlorophenyl)methyl]-3-methyl-4-[4-(propan-2-yl)phenyl]-4,5-dihydro-1H-1,2,4-triazol-5-one (C19H20ClN3O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
