1-[(4-Chlorophenyl)methyl]-3-methyl-4-(4-methylphenyl)-4,5-dihydro-1H-1,2,4-triazol-5-one CAS 860651-03-2 chemical structure

Description

The occurrence of 1-[(4-Chlorophenyl)methyl]-3-methyl-4-(4-methylphenyl)-4,5-dihydro-1H-1,2,4-triazol-5-one is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-[(4-Chlorophenyl)methyl]-3-methyl-4-(4-methylphenyl)-4,5-dihydro-1H-1,2,4-triazol-5-one (CAS 860651-03-2) is a high-purity analytical reference standard with the molecular formula C17H16ClN3O and a molecular weight of 313.78 g/mol.

The molecular framework of 1-[(4-Chlorophenyl)methyl]-3-methyl-4-(4-methylphenyl)-4,5-dihydro-1H-1,2,4-triazol-5-one (C17H16ClN3O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
