Chemical Structure

Penta-1,4-dien-3-one CAS 1890-28-4 chemical structure

Description

The occurrence of Penta-1,4-dien-3-one is closely related to a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Penta-1,4-dien-3-one (CAS 1890-28-4), molecular formula C5H6O and molecular weight 82.10 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C5H6O, Penta-1,4-dien-3-one contains a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 82.10 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), Penta-1,4-dien-3-one 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.
