Chemical Structure

3-Chlorocyclopent-2-en-1-one CAS 53102-14-0 chemical structure

Description

The molecular framework of 3-Chlorocyclopent-2-en-1-one (C5H5ClO) is characterized by a hydroxyl group, an ether linkage, chlorine substitution. 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).

3-Chlorocyclopent-2-en-1-one (CAS 53102-14-0) is a high-purity analytical reference standard with the molecular formula C5H5ClO and a molecular weight of 116.55 g/mol.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 3-Chlorocyclopent-2-en-1-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
