Chemical Structure
Description
5-(5-Bromopyridin-3-yl)-2,3-dihydro-1,3,4-oxadiazol-2-one (CAS 1186115-49-0), molecular formula C7H4BrN3O2 and molecular weight 242.03 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, 5-(5-Bromopyridin-3-yl)-2,3-dihydro-1,3,4-oxadiazol-2-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 242.03 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.
