Compared with other compounds in its class, the molecular weight of 82.10 g/mol gives 2-Cyclopenten-1-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Cyclopenten-1-one (CAS 930-30-3), molecular formula C5H6O and molecular weight 82.10 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Cyclopenten-1-one (C5H6O) is characterized by 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).
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 2-Cyclopenten-1-one 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.
