Chemical Structure

(3E,5E)-Hepta-3,5-dien-2-one CAS 18402-90-9 chemical structure

Description

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.

(3E,5E)-Hepta-3,5-dien-2-one (CAS 18402-90-9), molecular formula C7H10O and molecular weight 110.15 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a hydroxyl group, an ether linkage, (3E,5E)-Hepta-3,5-dien-2-one is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 110.15 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).

CATO manufactures (3E,5E)-Hepta-3,5-dien-2-one 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.
