Chemical Structure

Bis(2-diphenylphosphinophenyl) ether CAS 166330-10-5 chemical structure

Description

Bis(2-diphenylphosphinophenyl) ether (CAS 166330-10-5), molecular formula C36H28OP2 and molecular weight 538.55 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C36H28OP2, Bis(2-diphenylphosphinophenyl) ether contains organophosphorus functionality, a hydroxyl group, an ether linkage, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 538.55 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

As a certified reference material (CRM), Bis(2-diphenylphosphinophenyl) ether meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
