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 4-Bromo-7-fluorobenzo[d]thiazole.
CATO supplies 4-Bromo-7-fluorobenzo[d]thiazole (CAS 2778162-63-1), a certified reference material (molecular formula C7H3BrFNS, MW 232.07 g/mol) for analytical method development and quality control.
4-Bromo-7-fluorobenzo[d]thiazole (C7H3BrFNS) contains a nitrile group, sulfur-containing functionality, fluorine/bromine 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).
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.
