Phenyldi-m-tolylphosphine CAS 18803-08-2

Description

Compared with other compounds in its class, the molecular weight of 290.34 g/mol gives Phenyldi-m-tolylphosphine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Phenyldi-m-tolylphosphine (CAS 18803-08-2) is a high-purity analytical reference standard with the molecular formula C20H19P and a molecular weight of 290.34 g/mol.

Based on its molecular formula C20H19P, Phenyldi-m-tolylphosphine contains organophosphorus functionality, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 290.34 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.

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.
