Pyridine-3,5-dicarbonitrile CAS 1195-58-0

Description

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

Pyridine-3,5-dicarbonitrile (CAS 1195-58-0) is a high-purity analytical reference standard with the molecular formula C7H3N3 and a molecular weight of 129.12 g/mol.

Owing to a nitrile group, an aromatic ring system, Pyridine-3,5-dicarbonitrile is typically pale yellow to yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 129.12 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.

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.
