Description
CATO manufactures 2-Chloro-4,6-dimethyl-1,3-benzothiazole 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.
2-Chloro-4,6-dimethyl-1,3-benzothiazole (CAS 80689-35-6), molecular formula C9H8ClNS and molecular weight 197.68 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Chloro-4,6-dimethyl-1,3-benzothiazole (C9H8ClNS) 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. 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.
