4-Methyl-N-(quinoxalin-2-ylmethylene)aniline CAS 104182-64-1

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Methyl-N-(quinoxalin-2-ylmethylene)aniline.

4-Methyl-N-(quinoxalin-2-ylmethylene)aniline (CAS 104182-64-1) is a high-purity analytical reference standard with the molecular formula C16H13N3 and a molecular weight of 247.29 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 4-Methyl-N-(quinoxalin-2-ylmethylene)aniline is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 247.29 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).

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-Methyl-N-(quinoxalin-2-ylmethylene)aniline 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.
