Chemical Structure
Description
CATO supplies (1R,2S)-2-(N-Benzyl-2,4,6-trimethylphenylsulfonamido)-1-phenylpropyl propionate (CAS 187324-66-9), a certified reference material (molecular formula C28H33NO4S, MW 479.63 g/mol) for analytical method development and quality control.
(1R,2S)-2-(N-Benzyl-2,4,6-trimethylphenylsulfonamido)-1-phenylpropyl propionate (C28H33NO4S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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.
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.
