Chemical Structure

4-(p-Tolylamino)benzonitrile CAS 197173-65-2 chemical structure

Description

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 4-(p-Tolylamino)benzonitrile is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 208.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

4-(p-Tolylamino)benzonitrile (CAS 197173-65-2), molecular formula C14H12N2 and molecular weight 208.26 g/mol, is a CATO reference standard with documented purity and traceability.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 4-(p-Tolylamino)benzonitrile 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.
