Chemical Structure

2-Oxohex-5-enoic acid CAS 80003-58-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 128.13 g/mol gives 2-Oxohex-5-enoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Oxohex-5-enoic acid (CAS 80003-58-3) is a high-purity analytical reference standard with the molecular formula C6H8O3 and a molecular weight of 128.13 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 2-Oxohex-5-enoic acid is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 128.13 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).

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), 2-Oxohex-5-enoic acid 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.
