Chemical Structure
Description
The occurrence of 4-Bromo-6-chlorobenzo[d]thiazol-2-amine is closely related to a nitrile group, sulfur-containing functionality, chlorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 4-Bromo-6-chlorobenzo[d]thiazol-2-amine (CAS 38338-20-4), a certified reference material (molecular formula C7H4BrClN2S, MW 263.54 g/mol) for analytical method development and quality control.
Owing to a nitrile group, sulfur-containing functionality, chlorine/bromine substitution, an aromatic ring system, 4-Bromo-6-chlorobenzo[d]thiazol-2-amine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 263.54 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
