N-[2-[(4S)-4,5-Dihydro-4-(1-methylethyl)-2-oxazolyl]-6-[[(1S,2R,5S)-5-methyl-2-(1-methylethyl)cyclohexyl]oxy]phenyl]benzenesulfonamide (CAS 1192815-31-8) is a high-purity analytical reference standard with the molecular formula C28H38N2O4S and a molecular weight of 498.68 g/mol.
N-[2-[(4S)-4,5-Dihydro-4-(1-methylethyl)-2-oxazolyl]-6-[[(1S,2R,5S)-5-methyl-2-(1-methylethyl)cyclohexyl]oxy]phenyl]benzenesulfonamide (C28H38N2O4S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
