Chemical Structure

ethyl 3-oxo-2-(2-oxocyclopentyl)butanoate CAS 91353-01-4 chemical structure

Description

CATO manufactures ethyl 3-oxo-2-(2-oxocyclopentyl)butanoate 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.

ethyl 3-oxo-2-(2-oxocyclopentyl)butanoate (CAS 91353-01-4) is a high-purity analytical reference standard with the molecular formula C11H16O4 and a molecular weight of 212.24 g/mol.

The molecular framework of ethyl 3-oxo-2-(2-oxocyclopentyl)butanoate (C11H16O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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.
