Chemical Structure

(Difluoromethyl)bis(4-methoxyphenyl)phosphane CAS 2606917-44-4 chemical structure

Description

The occurrence of (Difluoromethyl)bis(4-methoxyphenyl)phosphane is closely related to organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(Difluoromethyl)bis(4-methoxyphenyl)phosphane (CAS 2606917-44-4) is a high-purity analytical reference standard with the molecular formula C15H15F2O2P and a molecular weight of 296.25 g/mol.

Based on its molecular formula C15H15F2O2P, (Difluoromethyl)bis(4-methoxyphenyl)phosphane contains organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 296.25 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), (Difluoromethyl)bis(4-methoxyphenyl)phosphane 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.
