Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Diphenyl(4-vinylphenyl)phosphineoxide (CAS 47182-95-6) is a high-purity analytical reference standard with the molecular formula C20H17OP and a molecular weight of 304.32 g/mol.
The molecular framework of Diphenyl(4-vinylphenyl)phosphineoxide (C20H17OP) 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).
CATO manufactures Diphenyl(4-vinylphenyl)phosphineoxide 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.
