Chemical Structure
Description
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.
CATO supplies 2-{[(4-chlorophenyl)sulfonyl]amino}-3-methyl-N-[3-(trifluoromethyl)phenyl]butanamide (CAS 317378-10-2), a certified reference material (molecular formula C18H18ClF3N2O3S, MW 434.86 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 2-{[(4-chlorophenyl)sulfonyl]amino}-3-methyl-N-[3-(trifluoromethyl)phenyl]butanamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 434.86 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.
