The occurrence of 5-((1H-1,2,4-triazol-1-yl)methyl)-3-(2,4-dichlorophenyl)-1H-1,2,4-triazole is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-((1H-1,2,4-triazol-1-yl)methyl)-3-(2,4-dichlorophenyl)-1H-1,2,4-triazole (CAS 338405-21-3), molecular formula C11H8Cl2N6 and molecular weight 295.13 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-((1H-1,2,4-triazol-1-yl)methyl)-3-(2,4-dichlorophenyl)-1H-1,2,4-triazole (C11H8Cl2N6) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
