Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(2-Chlorophenyl)-4-methyl-5-(methylthio)-4H-1,2,4-triazole.
CATO supplies 3-(2-Chlorophenyl)-4-methyl-5-(methylthio)-4H-1,2,4-triazole (CAS 116850-67-0), a certified reference material (molecular formula C10H10ClN3S, MW 239.72 g/mol) for analytical method development and quality control.
Based on its molecular formula C10H10ClN3S, 3-(2-Chlorophenyl)-4-methyl-5-(methylthio)-4H-1,2,4-triazole 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 239.72 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
