4-(4-Chlorophenyl)-5-[(4-methylphenyl)sulfanyl]-1,2,3-thiadiazole CAS 338408-55-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(4-Chlorophenyl)-5-[(4-methylphenyl)sulfanyl]-1,2,3-thiadiazole.

4-(4-Chlorophenyl)-5-[(4-methylphenyl)sulfanyl]-1,2,3-thiadiazole (CAS 338408-55-2), molecular formula C15H11ClN2S2 and molecular weight 318.84 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C15H11ClN2S2, 4-(4-Chlorophenyl)-5-[(4-methylphenyl)sulfanyl]-1,2,3-thiadiazole 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 318.84 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

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.
