Chemical Structure

2-(Phenylamino)isonicotinonitrile CAS 137225-05-9 chemical structure

Description

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 2-(Phenylamino)isonicotinonitrile is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 195.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

2-(Phenylamino)isonicotinonitrile (CAS 137225-05-9), molecular formula C12H9N3 and molecular weight 195.22 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), 2-(Phenylamino)isonicotinonitrile 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.
