2-{[(3,4-dichlorophenyl)methyl]sulfanyl}-6-[(E)-2-(4-methylphenyl)ethenyl]-4-[(Z)-2-(4-methylphenyl)ethenyl]pyridine-3-carbonitrile (CAS 303985-44-6) is a high-purity analytical reference standard with the molecular formula C31H24Cl2N2S and a molecular weight of 527.51 g/mol.
2-{[(3,4-dichlorophenyl)methyl]sulfanyl}-6-[(E)-2-(4-methylphenyl)ethenyl]-4-[(Z)-2-(4-methylphenyl)ethenyl]pyridine-3-carbonitrile (C31H24Cl2N2S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
