Chemical Structure
Description
The occurrence of Ethyl 5-cyclopentyl-5-oxovalerate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Ethyl 5-cyclopentyl-5-oxovalerate (CAS 24071-97-4), molecular formula C12H20O3 and molecular weight 212.29 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C12H20O3, Ethyl 5-cyclopentyl-5-oxovalerate contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 212.29 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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-cyclopentyl-5-oxovalerate 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.
