Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
N-(2,5-dibromothiophen-3-yl)acetamide (CAS 89581-54-4), molecular formula C6H5Br2NOS and molecular weight 298.98 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, N-(2,5-dibromothiophen-3-yl)acetamide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 298.98 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).
As a certified reference material (CRM), N-(2,5-dibromothiophen-3-yl)acetamide 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.
