Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, (S)-3-(4-Aminophenoxy)-N-((4-cyano-3-(trifluoromethyl)phenyl)carbamoyl)-2-hydroxy-2-methylpropanamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 422.36 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).
CATO supplies (S)-3-(4-Aminophenoxy)-N-((4-cyano-3-(trifluoromethyl)phenyl)carbamoyl)-2-hydroxy-2-methylpropanamide (CAS 850218-75-6), a certified reference material (molecular formula C19H17F3N4O4, MW 422.36 g/mol) for analytical method development and quality control.
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.
