[S(R)]-N-[(1S)-1-[2-(Diphenylphosphino)phenyl]-2,2-dimethylpropyl]-2-methyl-2-propanesulfinamide CAS 1595319-94-0 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 451.60 g/mol gives [S(R)]-N-[(1S)-1-[2-(Diphenylphosphino)phenyl]-2,2-dimethylpropyl]-2-methyl-2-propanesulfinamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

[S(R)]-N-[(1S)-1-[2-(Diphenylphosphino)phenyl]-2,2-dimethylpropyl]-2-methyl-2-propanesulfinamide (CAS 1595319-94-0), molecular formula C27H34NOPS and molecular weight 451.60 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, sulfur-containing functionality, organophosphorus functionality, a hydroxyl group, an ether linkage, [S(R)]-N-[(1S)-1-[2-(Diphenylphosphino)phenyl]-2,2-dimethylpropyl]-2-methyl-2-propanesulfinamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 451.60 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
