Chemical Structure
Description
The occurrence of Ethyl 1-(2-ethoxy-2-oxoethyl)-2-oxocyclopentane-1-carboxylate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Ethyl 1-(2-ethoxy-2-oxoethyl)-2-oxocyclopentane-1-carboxylate (CAS 41301-66-0), molecular formula C12H18O5 and molecular weight 242.27 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Ethyl 1-(2-ethoxy-2-oxoethyl)-2-oxocyclopentane-1-carboxylate (C12H18O5) 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 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 1-(2-ethoxy-2-oxoethyl)-2-oxocyclopentane-1-carboxylate 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.
