1,2-Bis(bis(3,5-dimethylphenyl)phosphino)ethane CAS 220185-35-3

Description

The occurrence of 1,2-Bis(bis(3,5-dimethylphenyl)phosphino)ethane is closely related to organophosphorus functionality, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1,2-Bis(bis(3,5-dimethylphenyl)phosphino)ethane (CAS 220185-35-3) is a high-purity analytical reference standard with the molecular formula C34H40P2 and a molecular weight of 510.63 g/mol.

Structurally, 1,2-Bis(bis(3,5-dimethylphenyl)phosphino)ethane (C34H40P2) contains organophosphorus functionality, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 510.63 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.
