5-Acetylpyrazine-2-carbonitrile CAS 916333-43-2 chemical structure

Description

As a certified reference material (CRM), 5-Acetylpyrazine-2-carbonitrile 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.

CATO supplies 5-Acetylpyrazine-2-carbonitrile (CAS 916333-43-2), a certified reference material (molecular formula C7H5N3O, MW 147.13 g/mol) for analytical method development and quality control.

5-Acetylpyrazine-2-carbonitrile (C7H5N3O) contains an amide group, a hydroxyl group, an ether linkage, an aromatic ring system. 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.
