Chemical Structure

(R)-5,5'-Heptamethylenedioxy-2,2'-bis(diphenylphosphino) biphenyl CAS 1225281-37-7 chemical structure

Description

(R)-5,5'-Heptamethylenedioxy-2,2'-bis(diphenylphosphino) biphenyl (C43H40O2P2) contains organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

(R)-5,5'-Heptamethylenedioxy-2,2'-bis(diphenylphosphino) biphenyl (CAS 1225281-37-7) is a high-purity analytical reference standard with the molecular formula C43H40O2P2 and a molecular weight of 650.72 g/mol.

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.
