As a certified reference material (CRM), 4-[3-(Trifluoromethyl)phenyl]-2-({[3-(trifluoromethyl)phenyl]methyl}sulfanyl)pyridine-3-carbonitrile meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
4-[3-(Trifluoromethyl)phenyl]-2-({[3-(trifluoromethyl)phenyl]methyl}sulfanyl)pyridine-3-carbonitrile (CAS 478245-79-3) is a high-purity analytical reference standard with the molecular formula C21H12F6N2S and a molecular weight of 438.39 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine substitution, 4-[3-(Trifluoromethyl)phenyl]-2-({[3-(trifluoromethyl)phenyl]methyl}sulfanyl)pyridine-3-carbonitrile is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 438.39 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
