Description

Compared with other compounds in its class, the molecular weight of 156.18 g/mol gives ethyl 3-methyl-4-oxopent-2-enoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

ethyl 3-methyl-4-oxopent-2-enoate (CAS 13979-23-2), molecular formula C8H12O3 and molecular weight 156.18 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of ethyl 3-methyl-4-oxopent-2-enoate (C8H12O3) 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.

As a certified reference material (CRM), ethyl 3-methyl-4-oxopent-2-enoate 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.
