Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Bromo-1-(thiazol-4-yl)ethan-1-one hydrobromide.
2-Bromo-1-(thiazol-4-yl)ethan-1-one hydrobromide (CAS 26489-43-0) is a high-purity analytical reference standard with the molecular formula C5H4BrNOSHBr and a molecular weight of 286.97 g/mol.
2-Bromo-1-(thiazol-4-yl)ethan-1-one hydrobromide (C5H4BrNOSHBr) contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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-1-(thiazol-4-yl)ethan-1-one hydrobromide 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.
