Chemical Structure

(10E,12Z)-10,12-Octadecadienoic Acid Methyl Ester CAS 21870-97-3 chemical structure

Description

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, (10E,12Z)-10,12-Octadecadienoic Acid Methyl Ester is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 294.47 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.

(10E,12Z)-10,12-Octadecadienoic Acid Methyl Ester (CAS 21870-97-3), molecular formula C19H34O2 and molecular weight 294.47 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.
