Chemical Structure
Description
2-Bromo-7-chlorobenzo[d]thiazole (CAS 3507-58-2) is a high-purity analytical reference standard with the molecular formula C7H3BrClNS and a molecular weight of 248.53 g/mol.
Owing to a nitrile group, sulfur-containing functionality, chlorine/bromine substitution, an aromatic ring system, 2-Bromo-7-chlorobenzo[d]thiazole is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 248.53 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-Bromo-7-chlorobenzo[d]thiazole meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
