Chemical Structure
Description
CATO supplies [(4-Chlorobut-2-yn-1-yl)sulfanyl]carbonitrile (CAS 113079-33-7), a certified reference material (molecular formula C5H4ClNS, MW 145.61 g/mol) for analytical method development and quality control.
Owing to a nitrile group, sulfur-containing functionality, chlorine substitution, [(4-Chlorobut-2-yn-1-yl)sulfanyl]carbonitrile is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 145.61 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 [(4-Chlorobut-2-yn-1-yl)sulfanyl]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.
