Chemical Structure

2,2-Bis(diphenylphosphino)-1-phenylethanone CAS 91381-27-0 chemical structure

Description

The occurrence of 2,2-Bis(diphenylphosphino)-1-phenylethanone is closely related to organophosphorus functionality, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2,2-Bis(diphenylphosphino)-1-phenylethanone (CAS 91381-27-0), molecular formula C32H26OP2 and molecular weight 488.50 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C32H26OP2, 2,2-Bis(diphenylphosphino)-1-phenylethanone 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 488.50 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
