Chemical Structure

Allyldiphenylphosphine oxide CAS 4141-48-4 chemical structure

Description

Owing to organophosphorus functionality, a hydroxyl group, an ether linkage, a polycyclic aromatic system, Allyldiphenylphosphine oxide is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 242.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Allyldiphenylphosphine oxide (CAS 4141-48-4) is a high-purity analytical reference standard with the molecular formula C15H15OP and a molecular weight of 242.25 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.

As a certified reference material (CRM), Allyldiphenylphosphine oxide 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.
