4-Phenylbenzonitrile CAS 2920-38-9

Description

Compared with other compounds in its class, the molecular weight of 179.22 g/mol gives 4-Phenylbenzonitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 4-Phenylbenzonitrile (CAS 2920-38-9), a certified reference material (molecular formula C13H9N, MW 179.22 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 4-Phenylbenzonitrile is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 179.22 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.

As a certified reference material (CRM), 4-Phenylbenzonitrile 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.
