Chemical Structure

(6Z,9Z)-Octadeca-6,9-dienoic acid CAS 28290-77-9 chemical structure

Description

CATO manufactures (6Z,9Z)-Octadeca-6,9-dienoic acid 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.

CATO supplies (6Z,9Z)-Octadeca-6,9-dienoic acid (CAS 28290-77-9), a certified reference material (molecular formula C18H32O2, MW 280.45 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, (6Z,9Z)-Octadeca-6,9-dienoic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 280.45 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.
