Chemical Structure
Description
5-Bromo-6-fluorobenzo[d]thiazole-2-thiol (C7H3BrFNS2) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO supplies 5-Bromo-6-fluorobenzo[d]thiazole-2-thiol (CAS 1881291-16-2), a certified reference material (molecular formula C7H3BrFNS2, MW 264.14 g/mol) for analytical method development and quality control.
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.
