Chemical Structure

α-methylbenzonitrile CAS 1823-91-2 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including α-methylbenzonitrile.

CATO supplies α-methylbenzonitrile (CAS 1823-91-2), a certified reference material (molecular formula C9H15N, MW 137.22 g/mol) for analytical method development and quality control.

Owing to a nitrile group, α-methylbenzonitrile is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 137.22 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), α-methylbenzonitrile 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.
