2-Methylpyridine-3,5-dicarbonitrile CAS 4523-28-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Methylpyridine-3,5-dicarbonitrile.

2-Methylpyridine-3,5-dicarbonitrile (CAS 4523-28-8) is a high-purity analytical reference standard with the molecular formula C8H5N3 and a molecular weight of 143.15 g/mol.

The molecular framework of 2-Methylpyridine-3,5-dicarbonitrile (C8H5N3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
