Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 330.50 g/mol gives ethyl (5E,8Z,11Z,14E,17Z)-icosa-5,8,11,14,17-pentaenoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
ethyl (5E,8Z,11Z,14E,17Z)-icosa-5,8,11,14,17-pentaenoate (CAS CATO-C4X-289027) 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,14E,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.
As a certified reference material (CRM), ethyl (5E,8Z,11Z,14E,17Z)-icosa-5,8,11,14,17-pentaenoate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
