Chemical Structure
Description
CATO supplies Ethyl cyclopent-2-enecarboxylate (CAS 5809-02-9), a certified reference material (molecular formula C8H12O2, MW 140.18 g/mol) for analytical method development and quality control.
The molecular framework of Ethyl cyclopent-2-enecarboxylate (C8H12O2) is characterized by a carboxylic acid group, 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).
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 Ethyl cyclopent-2-enecarboxylate 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.
