Description
CATO manufactures 1,3-Benzothiazole-6-carbonyl chloride 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.
1,3-Benzothiazole-6-carbonyl chloride (CAS 55439-73-1), molecular formula C8H4ClNOS and molecular weight 197.64 g/mol, is a CATO reference standard with documented purity and traceability.
1,3-Benzothiazole-6-carbonyl chloride (C8H4ClNOS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
