CATO manufactures 2-Chloro-6-fluorobenzothiazole 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-6-fluorobenzothiazole (CAS 399-74-6), molecular formula C7H3ClFNS and molecular weight 187.62 g/mol, is a CATO reference standard with documented purity and traceability.
2-Chloro-6-fluorobenzothiazole (C7H3ClFNS) contains a nitrile group, sulfur-containing functionality, fluorine/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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
