Chemical Structure
Description
The occurrence of Bis(2-diphenylphosphino)ethyl ether 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.
Bis(2-diphenylphosphino)ethyl ether (CAS 50595-38-5), molecular formula C28H28OP2 and molecular weight 442.47 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Bis(2-diphenylphosphino)ethyl ether (C28H28OP2) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Bis(2-diphenylphosphino)ethyl ether 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.
