Description
As a certified reference material (CRM), 4,4-Difluoro-1-phenylcyclohexanecarbonitrile 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.
4,4-Difluoro-1-phenylcyclohexanecarbonitrile (CAS 1246744-42-2), molecular formula C13H13F2N and molecular weight 221.25 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution, 4,4-Difluoro-1-phenylcyclohexanecarbonitrile is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 221.25 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.
