Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
CATO supplies 5-(3-Chloro-phenyl)-4-(2,5-dimethyl-phenyl)-4H-[1,2,4]triazole-3-thiol (CAS 519151-96-3), a certified reference material (molecular formula C16H14ClN3S, MW 315.82 g/mol) for analytical method development and quality control.
5-(3-Chloro-phenyl)-4-(2,5-dimethyl-phenyl)-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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
