Chemical Structure
Description
As a certified reference material (CRM), 2-(4-Nitrophenyl)-2-oxoethyl acetate 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 2-(4-Nitrophenyl)-2-oxoethyl acetate (CAS 65921-30-4), a certified reference material (molecular formula C10H9NO5, MW 223.18 g/mol) for analytical method development and quality control.
2-(4-Nitrophenyl)-2-oxoethyl acetate (C10H9NO5) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; 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.
