Chemical Structure
Description
8-Oxo-8-(3-phenoxyphenyl)octanoic acid (CAS 951888-79-2), molecular formula C20H22O4 and molecular weight 326.39 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 8-Oxo-8-(3-phenoxyphenyl)octanoic acid (C20H22O4) is characterized by a flavonoid 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 8-Oxo-8-(3-phenoxyphenyl)octanoic acid 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.
