Chemical Structure
Description
The occurrence of (2-(Diphenylphosphino)-1-hydroxyethyl)diphenylphosphine oxide is closely related to a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(2-(Diphenylphosphino)-1-hydroxyethyl)diphenylphosphine oxide (CAS 65220-79-3) is a high-purity analytical reference standard with the molecular formula C26H24O2P2 and a molecular weight of 430.42 g/mol.
The molecular framework of (2-(Diphenylphosphino)-1-hydroxyethyl)diphenylphosphine oxide (C26H24O2P2) 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), (2-(Diphenylphosphino)-1-hydroxyethyl)diphenylphosphine 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.
