1,1'-[(1S)-4,4'-Bis(trimethylsilyl)[1,1'-binaphthalene]-2,2'-diyl]bis[1,1-diphenylphosphine] CAS 933996-97-5 chemical structure

Description

The occurrence of 1,1'-[(1S)-4,4'-Bis(trimethylsilyl)[1,1'-binaphthalene]-2,2'-diyl]bis[1,1-diphenylphosphine] is closely related to organophosphorus functionality, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 1,1'-[(1S)-4,4'-Bis(trimethylsilyl)[1,1'-binaphthalene]-2,2'-diyl]bis[1,1-diphenylphosphine] (CAS 933996-97-5), a certified reference material (molecular formula C50H48P2Si2, MW 767.03 g/mol) for analytical method development and quality control.

The molecular framework of 1,1'-[(1S)-4,4'-Bis(trimethylsilyl)[1,1'-binaphthalene]-2,2'-diyl]bis[1,1-diphenylphosphine] (C50H48P2Si2) is characterized by organophosphorus functionality, a polycyclic aromatic system. 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. 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.
