Chemical Structure

Methyl (S,9Z,11E)-13-hydroxyoctadeca-9,11-dienoate CAS 109837-85-6 chemical structure

Description

Methyl (S,9Z,11E)-13-hydroxyoctadeca-9,11-dienoate (CAS 109837-85-6), molecular formula C19H34O3 and molecular weight 310.47 g/mol, is a CATO reference standard with documented purity and traceability.

Methyl (S,9Z,11E)-13-hydroxyoctadeca-9,11-dienoate (C19H34O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
