Chemical Structure
Description
The occurrence of 6-Bromo-5-chlorobenzo[d]thiazole 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.
6-Bromo-5-chlorobenzo[d]thiazole (CAS 1361380-51-9), molecular formula C7H3BrClNS and molecular weight 248.53 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C7H3BrClNS, 6-Bromo-5-chlorobenzo[d]thiazole contains a nitrile group, sulfur-containing functionality, chlorine/bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 248.53 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
