Chemical Structure
Description
The occurrence of 2-{[(3,4-dichlorophenyl)methyl]sulfanyl}-4-methyl-6-phenylpyridine-3-carbonitrile is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-{[(3,4-dichlorophenyl)methyl]sulfanyl}-4-methyl-6-phenylpyridine-3-carbonitrile (CAS 341967-45-1), molecular formula C20H14Cl2N2S and molecular weight 385.31 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-{[(3,4-dichlorophenyl)methyl]sulfanyl}-4-methyl-6-phenylpyridine-3-carbonitrile (C20H14Cl2N2S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
CATO manufactures 2-{[(3,4-dichlorophenyl)methyl]sulfanyl}-4-methyl-6-phenylpyridine-3-carbonitrile under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
