Chemical Structure
Description
Based on its molecular formula C8H5BrClNOS, 5-bromo-2-chloro-6-methoxybenzo[d]thiazole, 97% contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 278.55 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.
CATO supplies 5-bromo-2-chloro-6-methoxybenzo[d]thiazole, 97% (CAS 1247348-76-0), a certified reference material (molecular formula C8H5BrClNOS, MW 278.55 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.
