Chemical Structure
Description
The occurrence of (9Z,12Z,15E)-octadeca-9,12,15-trienoic acid is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(9Z,12Z,15E)-octadeca-9,12,15-trienoic acid (CAS CATO-C3D-262918) is a high-purity analytical reference standard with the molecular formula C18H30O2 and a molecular weight of 278.43 g/mol.
Owing to a steroid core, a hydroxyl group, an ether linkage, (9Z,12Z,15E)-octadeca-9,12,15-trienoic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 278.43 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
