N-((1S,2S)-2-Amino-1,2-diphenylethyl)benzenesulfonamide (CAS 300345-91-9) is a high-purity analytical reference standard with the molecular formula C20H20N2O2S and a molecular weight of 352.45 g/mol.
N-((1S,2S)-2-Amino-1,2-diphenylethyl)benzenesulfonamide (C20H20N2O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
