Description
As a certified reference material (CRM), 5-Bromo-2-(1H-imidazol-1-yl)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.
5-Bromo-2-(1H-imidazol-1-yl)thiazole (CAS 446287-07-6) is a high-purity analytical reference standard with the molecular formula C6H4BrN3S and a molecular weight of 230.09 g/mol.
Owing to a nitrile group, sulfur-containing functionality, bromine substitution, an aromatic ring system, 5-Bromo-2-(1H-imidazol-1-yl)thiazole is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 230.09 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
