Chemical Structure

ethyl(5E,8Z,11Z,14Z,17Z)-icosa-5,8,11,14,17-pentaenoate CAS 125827-50-1 chemical structure

Description

ethyl(5E,8Z,11Z,14Z,17Z)-icosa-5,8,11,14,17-pentaenoate (CAS 125827-50-1) is a high-purity analytical reference standard with the molecular formula C22H34O2 and a molecular weight of 330.50 g/mol.

Owing to a steroid core, a hydroxyl group, an ether linkage, ethyl(5E,8Z,11Z,14Z,17Z)-icosa-5,8,11,14,17-pentaenoate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 330.50 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.
