Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 128.13 g/mol gives Methyl 4-oxopent-2-enoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Methyl 4-oxopent-2-enoate (CAS 4188-88-9), molecular formula C6H8O3 and molecular weight 128.13 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Methyl 4-oxopent-2-enoate (C6H8O3) 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 Methyl 4-oxopent-2-enoate 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.
