Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(4-Fluorophenyl)-2-thioxo-6-(trifluoromethyl)-2,3-dihydropyridine-3-carbonitrile.
CATO supplies 4-(4-Fluorophenyl)-2-thioxo-6-(trifluoromethyl)-2,3-dihydropyridine-3-carbonitrile (CAS 832741-30-7), a certified reference material (molecular formula C13H6F4N2S, MW 298.26 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine substitution, 4-(4-Fluorophenyl)-2-thioxo-6-(trifluoromethyl)-2,3-dihydropyridine-3-carbonitrile is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 298.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
