Chemical Structure
Description
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, (12Z,15Z)-10-Hydroxyoctadeca-12,15-dienoic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 296.44 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).
(12Z,15Z)-10-Hydroxyoctadeca-12,15-dienoic acid (CAS 34932-14-4), molecular formula C18H32O3 and molecular weight 296.44 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
