Chemical Structure

2-[(3-Chlorophenyl)sulfanyl]-4-[3-(trifluoromethyl)phenyl]pyridine-3-carbonitrile CAS 478245-71-5 chemical structure

Description

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.

2-[(3-Chlorophenyl)sulfanyl]-4-[3-(trifluoromethyl)phenyl]pyridine-3-carbonitrile (CAS 478245-71-5) is a high-purity analytical reference standard with the molecular formula C19H10ClF3N2S and a molecular weight of 390.81 g/mol.

2-[(3-Chlorophenyl)sulfanyl]-4-[3-(trifluoromethyl)phenyl]pyridine-3-carbonitrile (C19H10ClF3N2S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine/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).

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.
