Description
As a certified reference material (CRM), 2-Cyano-3-(3,4-dimethylphenyl)propiophenone 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.
2-Cyano-3-(3,4-dimethylphenyl)propiophenone (CAS 898755-71-0), molecular formula C18H17NO and molecular weight 263.33 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 2-Cyano-3-(3,4-dimethylphenyl)propiophenone is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 263.33 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.
