Description
CATO supplies 5-Chlorobenzo[b]thiophene-2-carbonitrile (CAS 23622-24-4), a certified reference material (molecular formula C9H4ClNS, MW 193.65 g/mol) for analytical method development and quality control.
The molecular framework of 5-Chlorobenzo[b]thiophene-2-carbonitrile (C9H4ClNS) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 5-Chlorobenzo[b]thiophene-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.
