Chemical Structure

4,4'-Diphenoxybenzophenone CAS 14984-21-5 chemical structure

Description

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.

4,4'-Diphenoxybenzophenone (CAS 14984-21-5) is a high-purity analytical reference standard with the molecular formula C25H18O3 and a molecular weight of 366.41 g/mol.

The molecular framework of 4,4'-Diphenoxybenzophenone (C25H18O3) is characterized by a steroid core, 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.

CATO manufactures 4,4'-Diphenoxybenzophenone 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.
