Bis[2-[bis(2-methylphenyl)phosphino]phenyl]ether CAS 205497-64-9

Description

CATO supplies Bis[2-[bis(2-methylphenyl)phosphino]phenyl]ether (CAS 205497-64-9), a certified reference material (molecular formula C40H36OP2, MW 594.66 g/mol) for analytical method development and quality control.

Structurally, Bis[2-[bis(2-methylphenyl)phosphino]phenyl]ether (C40H36OP2) contains organophosphorus functionality, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 23.0, corresponding to approximately 23 ring(s) or double-bond equivalent(s). With a molecular weight of 594.66 g/mol, it falls into the moderately-high-molecular-weight range. 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.
