Chemical Structure

ethyl (5Z,8E,11Z,14Z,17Z)-icosa-5,8,11,14,17-pentaenoate CAS 125827-49-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 330.50 g/mol gives ethyl (5Z,8E,11Z,14Z,17Z)-icosa-5,8,11,14,17-pentaenoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

ethyl (5Z,8E,11Z,14Z,17Z)-icosa-5,8,11,14,17-pentaenoate (CAS 125827-49-8) is a high-purity analytical reference standard with the molecular formula C22H34O2 and a molecular weight of 330.50 g/mol.

Based on its molecular formula C22H34O2, ethyl (5Z,8E,11Z,14Z,17Z)-icosa-5,8,11,14,17-pentaenoate contains a steroid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 330.50 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
