2-((3-Chlorophenyl)thio)-5-(3-(trifluoromethyl)phenyl)nicotinonitrile CAS 338964-73-1

Description

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.

2-((3-Chlorophenyl)thio)-5-(3-(trifluoromethyl)phenyl)nicotinonitrile (CAS 338964-73-1), molecular formula C19H10ClF3N2S and molecular weight 390.81 g/mol, is a CATO reference standard with documented purity and traceability.

2-((3-Chlorophenyl)thio)-5-(3-(trifluoromethyl)phenyl)nicotinonitrile (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. 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.
