Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,4-Dibromo-6-fluorobenzothiazole.
2,4-Dibromo-6-fluorobenzothiazole (CAS 1188139-53-8), molecular formula C7H2Br2FNS and molecular weight 310.97 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2,4-Dibromo-6-fluorobenzothiazole (C7H2Br2FNS) is characterized by a nitrile group, sulfur-containing functionality, fluorine/bromine 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
