Description
CATO supplies 4-Oxotetrahydro-2H-pyran-3-carbonitrile (CAS 1368346-22-8), a certified reference material (molecular formula C6H7NO2, MW 125.13 g/mol) for analytical method development and quality control.
4-Oxotetrahydro-2H-pyran-3-carbonitrile (C6H7NO2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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.
As a certified reference material (CRM), 4-Oxotetrahydro-2H-pyran-3-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.
