Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Chloro-6-methyl-1-benzothiophene-2-carbonitrile.
CATO supplies 3-Chloro-6-methyl-1-benzothiophene-2-carbonitrile (CAS 137997-26-3), a certified reference material (molecular formula C10H6ClNS, MW 207.68 g/mol) for analytical method development and quality control.
Based on its molecular formula C10H6ClNS, 3-Chloro-6-methyl-1-benzothiophene-2-carbonitrile 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 207.68 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 3-Chloro-6-methyl-1-benzothiophene-2-carbonitrile 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.
