Chemical Structure
Description
4,5,7-Trifluorobenzo[d]thiazole-2(3H)-thione (CAS 179178-91-7), molecular formula C7H2F3NS2 and molecular weight 221.22 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4,5,7-Trifluorobenzo[d]thiazole-2(3H)-thione (C7H2F3NS2) 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 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.
CATO manufactures 4,5,7-Trifluorobenzo[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.
