Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Dimethylphenyl diphenyl phosphate.
Dimethylphenyl diphenyl phosphate (CAS 29660-68-2) is a high-purity analytical reference standard with the molecular formula C20H19O4P and a molecular weight of 354.34 g/mol.
The molecular framework of Dimethylphenyl diphenyl phosphate (C20H19O4P) is characterized by a flavonoid core, a phosphate ester group, 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 Dimethylphenyl diphenyl phosphate 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.
