Chemical Structure
Description
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
5-(3-Chlorophenyl)-4-(4-methylphenyl)-4h-1,2,4-triazole-3-thiol (CAS 893725-08-1) is a high-purity analytical reference standard with the molecular formula C15H12ClN3S and a molecular weight of 301.79 g/mol.
5-(3-Chlorophenyl)-4-(4-methylphenyl)-4h-1,2,4-triazole-3-thiol (C15H12ClN3S) 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.
