Chemical Structure
Description
Benzyl Diphenyl Phosphate (CAS 4218-62-6) is a high-purity analytical reference standard with the molecular formula C19H17O4P and a molecular weight of 340.31 g/mol.
Owing to a flavonoid core, a phosphate ester group, a hydroxyl group, an ether linkage, Benzyl Diphenyl Phosphate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 340.31 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures Benzyl 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.
