Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-((2-Bromobenzylidene)amino)-3-(3-chlorophenyl)-1H-1,2,4-triazole-5(4H)-thione.
CATO supplies 4-((2-Bromobenzylidene)amino)-3-(3-chlorophenyl)-1H-1,2,4-triazole-5(4H)-thione (CAS 478254-91-0), a certified reference material (molecular formula C15H10BrClN4S, MW 393.69 g/mol) for analytical method development and quality control.
Based on its molecular formula C15H10BrClN4S, 4-((2-Bromobenzylidene)amino)-3-(3-chlorophenyl)-1H-1,2,4-triazole-5(4H)-thione contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 393.69 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 4-((2-Bromobenzylidene)amino)-3-(3-chlorophenyl)-1H-1,2,4-triazole-5(4H)-thione under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
