Chemical Structure

Ethyl 5-(4-acetoxyphenyl)-5-oxopentanoate CAS 898758-85-5 chemical structure

Description

The occurrence of Ethyl 5-(4-acetoxyphenyl)-5-oxopentanoate is closely related to a flavonoid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Ethyl 5-(4-acetoxyphenyl)-5-oxopentanoate (CAS 898758-85-5) is a high-purity analytical reference standard with the molecular formula C15H18O5 and a molecular weight of 278.30 g/mol.

The molecular framework of Ethyl 5-(4-acetoxyphenyl)-5-oxopentanoate (C15H18O5) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, 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).

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 Ethyl 5-(4-acetoxyphenyl)-5-oxopentanoate 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.
