Chemical Structure

1,1,1-Tris(diphenylphosphino)methane CAS 28926-65-0 chemical structure

Description

The occurrence of 1,1,1-Tris(diphenylphosphino)methane is closely related to organophosphorus functionality, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1,1,1-Tris(diphenylphosphino)methane (CAS 28926-65-0), molecular formula C37H31P3 and molecular weight 568.56 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C37H31P3, 1,1,1-Tris(diphenylphosphino)methane contains organophosphorus functionality, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 568.56 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), 1,1,1-Tris(diphenylphosphino)methane 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.
