2-Amino-6-chloro-4-phenylpyridine-3,5-dicarbonitrile CAS 96583-92-5

Description

2-Amino-6-chloro-4-phenylpyridine-3,5-dicarbonitrile (CAS 96583-92-5), molecular formula C13H7ClN4 and molecular weight 254.67 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 2-Amino-6-chloro-4-phenylpyridine-3,5-dicarbonitrile is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 254.67 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
