2-Chloro-4-phenyl-6-(p-tolyl)nicotinonitrile CAS 38477-47-3

Description

Compared with other compounds in its class, the molecular weight of 304.77 g/mol gives 2-Chloro-4-phenyl-6-(p-tolyl)nicotinonitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Chloro-4-phenyl-6-(p-tolyl)nicotinonitrile (CAS 38477-47-3), molecular formula C19H13ClN2 and molecular weight 304.77 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C19H13ClN2, 2-Chloro-4-phenyl-6-(p-tolyl)nicotinonitrile contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 304.77 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
