The occurrence of 3-(2-Chlorophenyl)-5-((2,6-dichlorobenzyl)thio)-4-phenyl-4H-1,2,4-triazole is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-(2-Chlorophenyl)-5-((2,6-dichlorobenzyl)thio)-4-phenyl-4H-1,2,4-triazole (CAS 443741-19-3), molecular formula C21H14Cl3N3S and molecular weight 446.78 g/mol, is a CATO reference standard with documented purity and traceability.
3-(2-Chlorophenyl)-5-((2,6-dichlorobenzyl)thio)-4-phenyl-4H-1,2,4-triazole (C21H14Cl3N3S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
