Chemical Structure
Description
The occurrence of 5-(2-Chlorophenyl)-4-(2,5-dimethylphenyl)-4H-1,2,4-triazole-3-thiol 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.
CATO supplies 5-(2-Chlorophenyl)-4-(2,5-dimethylphenyl)-4H-1,2,4-triazole-3-thiol (CAS 519152-66-0), a certified reference material (molecular formula C16H14ClN3S, MW 315.82 g/mol) for analytical method development and quality control.
5-(2-Chlorophenyl)-4-(2,5-dimethylphenyl)-4H-1,2,4-triazole-3-thiol (C16H14ClN3S) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 5-(2-Chlorophenyl)-4-(2,5-dimethylphenyl)-4H-1,2,4-triazole-3-thiol under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
