Chemical Structure

(S)-2-(2'-(Diphenylphosphanyl)-[1,1'-biphenyl]-2-yl)-4-isopropyl-4,5-dihydrooxazole CAS 904887-75-8 chemical structure

Description

The occurrence of (S)-2-(2'-(Diphenylphosphanyl)-[1,1'-biphenyl]-2-yl)-4-isopropyl-4,5-dihydrooxazole is closely related to a steroid core, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (S)-2-(2'-(Diphenylphosphanyl)-[1,1'-biphenyl]-2-yl)-4-isopropyl-4,5-dihydrooxazole (CAS 904887-75-8), a certified reference material (molecular formula C30H28NOP, MW 449.52 g/mol) for analytical method development and quality control.

Owing to a steroid core, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage, (S)-2-(2'-(Diphenylphosphanyl)-[1,1'-biphenyl]-2-yl)-4-isopropyl-4,5-dihydrooxazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 449.52 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
