4-(2,4-Dichlorophenyl)-6-(4-methylphenyl)-2-(pyrrolidin-1-yl)pyridine-3-carbonitrile CAS 341964-92-9

Description

The occurrence of 4-(2,4-Dichlorophenyl)-6-(4-methylphenyl)-2-(pyrrolidin-1-yl)pyridine-3-carbonitrile is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-(2,4-Dichlorophenyl)-6-(4-methylphenyl)-2-(pyrrolidin-1-yl)pyridine-3-carbonitrile (CAS 341964-92-9), molecular formula C23H19Cl2N3 and molecular weight 408.32 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C23H19Cl2N3, 4-(2,4-Dichlorophenyl)-6-(4-methylphenyl)-2-(pyrrolidin-1-yl)pyridine-3-carbonitrile 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 408.32 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
