Chemical Structure
Description
6-[3-(Trifluoromethyl)phenyl]-2-{[3-(trifluoromethyl)phenyl]sulfanyl}pyridine-3-carbonitrile (CAS 252060-04-1) is a high-purity analytical reference standard with the molecular formula C20H10F6N2S and a molecular weight of 424.36 g/mol.
6-[3-(Trifluoromethyl)phenyl]-2-{[3-(trifluoromethyl)phenyl]sulfanyl}pyridine-3-carbonitrile (C20H10F6N2S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
