Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 410.44 g/mol gives Bis(3,5-dimethylphenyl) (4-ethylphenyl) phosphate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Bis(3,5-dimethylphenyl) (4-ethylphenyl) phosphate (CAS 7144-07-2) is a high-purity analytical reference standard with the molecular formula C24H27O4P and a molecular weight of 410.44 g/mol.
The molecular framework of Bis(3,5-dimethylphenyl) (4-ethylphenyl) phosphate (C24H27O4P) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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(3,5-dimethylphenyl) (4-ethylphenyl) 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.
