Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 322.34 g/mol gives Di(p-methoxyphenyl)phenylphosphine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Di(p-methoxyphenyl)phenylphosphine (CAS 14180-51-9) is a high-purity analytical reference standard with the molecular formula C20H19O2P and a molecular weight of 322.34 g/mol.
The molecular framework of Di(p-methoxyphenyl)phenylphosphine (C20H19O2P) is characterized by a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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).
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.
CATO manufactures Di(p-methoxyphenyl)phenylphosphine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
