Chemical Structure

(4S,5S)-1,3-Dibenzyl-4,5-diphenyl-1,3,2-diazaphospholidine 2-oxide CAS 138421-34-8 chemical structure

Description

Based on its molecular formula C28H27N2OP, (4S,5S)-1,3-Dibenzyl-4,5-diphenyl-1,3,2-diazaphospholidine 2-oxide contains a steroid core, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 438.50 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO supplies (4S,5S)-1,3-Dibenzyl-4,5-diphenyl-1,3,2-diazaphospholidine 2-oxide (CAS 138421-34-8), a certified reference material (molecular formula C28H27N2OP, MW 438.50 g/mol) for analytical method development and quality control.

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.
