Chemical Structure
Description
(S)-2-Methyl-N-[(2S)-1,1,1-trifluoro-4-oxo-4-phenylbutan-2-yl]propane-2-sulfinamide (CAS 1280655-24-4), molecular formula C14H18F3NO2S and molecular weight 321.36 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C14H18F3NO2S, (S)-2-Methyl-N-[(2S)-1,1,1-trifluoro-4-oxo-4-phenylbutan-2-yl]propane-2-sulfinamide contains a nitrogen-containing heterocyclic scaffold, 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 321.36 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
