Chemical Structure

Dimethyl(phenyl)phosphine CAS 672-66-2 chemical structure

Description

The molecular framework of Dimethyl(phenyl)phosphine (C8H11P) is characterized by organophosphorus functionality. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

Dimethyl(phenyl)phosphine (CAS 672-66-2) is a high-purity analytical reference standard with the molecular formula C8H11P and a molecular weight of 138.15 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.

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.
