Chemical Structure
Description
The occurrence of N-(2,4-difluorophenyl)-2-(N-phenylphenylsulfonamido)acetamide is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
N-(2,4-difluorophenyl)-2-(N-phenylphenylsulfonamido)acetamide (CAS 339102-95-3), molecular formula C20H16F2N2O3S and molecular weight 402.41 g/mol, is a CATO reference standard with documented purity and traceability.
N-(2,4-difluorophenyl)-2-(N-phenylphenylsulfonamido)acetamide (C20H16F2N2O3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
