[S(R)]-N-[(1S)-2-(Diphenylphosphino)-1-phenylethyl]-2-methyl-2-propanesulfinamide CAS 1803239-44-2

Description

[S(R)]-N-[(1S)-2-(Diphenylphosphino)-1-phenylethyl]-2-methyl-2-propanesulfinamide (CAS 1803239-44-2) is a high-purity analytical reference standard with the molecular formula C24H28NOPS and a molecular weight of 409.52 g/mol.

The molecular framework of [S(R)]-N-[(1S)-2-(Diphenylphosphino)-1-phenylethyl]-2-methyl-2-propanesulfinamide (C24H28NOPS) is characterized by a steroid core, an amide group, sulfur-containing functionality, organophosphorus functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
