(E)-Ethyl 3-oxohex-4-enoate CAS 25654-09-5

Description

Compared with other compounds in its class, the molecular weight of 156.18 g/mol gives (E)-Ethyl 3-oxohex-4-enoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies (E)-Ethyl 3-oxohex-4-enoate (CAS 25654-09-5), a certified reference material (molecular formula C8H12O3, MW 156.18 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, (E)-Ethyl 3-oxohex-4-enoate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 156.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 (E)-Ethyl 3-oxohex-4-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.
