Chemical Structure

Dicyclohexyl(2',4'-dimethyl-[1,1'-biphenyl]-2-yl)phosphine CAS 298205-49-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 378.53 g/mol gives Dicyclohexyl(2',4'-dimethyl-[1,1'-biphenyl]-2-yl)phosphine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Dicyclohexyl(2',4'-dimethyl-[1,1'-biphenyl]-2-yl)phosphine (CAS 298205-49-9), molecular formula C26H35P and molecular weight 378.53 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C26H35P, Dicyclohexyl(2',4'-dimethyl-[1,1'-biphenyl]-2-yl)phosphine contains organophosphorus functionality, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 378.53 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.
