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 7-Oxo-7-(3-phenoxyphenyl)heptanoic acid.
7-Oxo-7-(3-phenoxyphenyl)heptanoic acid (CAS 871127-76-3), molecular formula C19H20O4 and molecular weight 312.36 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 7-Oxo-7-(3-phenoxyphenyl)heptanoic acid (C19H20O4) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 7-Oxo-7-(3-phenoxyphenyl)heptanoic 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.
