Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(6-Dimethylamino-4-trifluoromethyl-pyridin-2-yl)-thiobenzoic acid S-(4-chloro-phenyl) ester.
CATO supplies 4-(6-Dimethylamino-4-trifluoromethyl-pyridin-2-yl)-thiobenzoic acid S-(4-chloro-phenyl) ester (CAS 1923177-13-2), a certified reference material (molecular formula C21H16ClF3N2OS, MW 436.88 g/mol) for analytical method development and quality control.
Based on its molecular formula C21H16ClF3N2OS, 4-(6-Dimethylamino-4-trifluoromethyl-pyridin-2-yl)-thiobenzoic acid S-(4-chloro-phenyl) ester contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 436.88 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
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.
