Chemical Structure
Description
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.
N-((1S,2S)-2-Amino-1,2-diphenylethyl)-4-(trifluoromethyl)benzenesulfonamide (CAS 410096-73-0), molecular formula C21H19F3N2O2S and molecular weight 420.45 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C21H19F3N2O2S, N-((1S,2S)-2-Amino-1,2-diphenylethyl)-4-(trifluoromethyl)benzenesulfonamide contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 420.45 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
