Chemical Structure
Description
As a certified reference material (CRM), Oxazole-2,4-diamine 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.
Oxazole-2,4-diamine (CAS 832134-07-3) is a high-purity analytical reference standard with the molecular formula C3H5N3O and a molecular weight of 99.09 g/mol.
Oxazole-2,4-diamine (C3H5N3O) contains an amide group, a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; 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.
