Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]methyl}phenyl N-(3,4-dichlorophenyl)carbamate (CAS 339019-96-4), molecular formula C20H12Cl3F3N2O2 and molecular weight 475.68 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C20H12Cl3F3N2O2, 4-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]methyl}phenyl N-(3,4-dichlorophenyl)carbamate contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 475.68 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
