Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including [S(R)]-N-[(S)-[3,5-Bis(1,1-dimethylethyl)-4-methoxyphenyl][2-(diphenylphosphino)phenyl]methyl]-2-methyl-2-propanesulfinamide.
CATO supplies [S(R)]-N-[(S)-[3,5-Bis(1,1-dimethylethyl)-4-methoxyphenyl][2-(diphenylphosphino)phenyl]methyl]-2-methyl-2-propanesulfinamide (CAS 1616688-63-1), a certified reference material (molecular formula C38H48NO2PS, MW 613.83 g/mol) for analytical method development and quality control.
Based on its molecular formula C38H48NO2PS, [S(R)]-N-[(S)-[3,5-Bis(1,1-dimethylethyl)-4-methoxyphenyl][2-(diphenylphosphino)phenyl]methyl]-2-methyl-2-propanesulfinamide contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, organophosphorus functionality, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 613.83 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
