Chemical Structure
Description
5,6-Difluorobenzo[d]thiazole-2(3H)-thione (CAS 786657-48-5), molecular formula C7H3F2NS2 and molecular weight 203.23 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5,6-Difluorobenzo[d]thiazole-2(3H)-thione (C7H3F2NS2) is characterized by a nitrile group, sulfur-containing functionality, fluorine substitution, an aromatic ring system. 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 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 5,6-Difluorobenzo[d]thiazole-2(3H)-thione 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.
