Description
CATO manufactures 7-Chloro-3-methyl-1-benzothiophene 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.
CATO supplies 7-Chloro-3-methyl-1-benzothiophene (CAS 17514-68-0), a certified reference material (molecular formula C9H7ClS, MW 182.67 g/mol) for analytical method development and quality control.
7-Chloro-3-methyl-1-benzothiophene (C9H7ClS) contains sulfur-containing functionality, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
