Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(5-((3-Chlorobenzyl)thio)-4-methyl-4H-1,2,4-triazol-3-yl)-2-(4-chlorophenyl)thiazole.
CATO supplies 4-(5-((3-Chlorobenzyl)thio)-4-methyl-4H-1,2,4-triazol-3-yl)-2-(4-chlorophenyl)thiazole (CAS 338760-90-0), a certified reference material (molecular formula C19H14Cl2N4S2, MW 433.38 g/mol) for analytical method development and quality control.
Based on its molecular formula C19H14Cl2N4S2, 4-(5-((3-Chlorobenzyl)thio)-4-methyl-4H-1,2,4-triazol-3-yl)-2-(4-chlorophenyl)thiazole contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 433.38 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
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.
