Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 336.55 g/mol gives (11Z,14Z)-Ethyl icosa-11,14-dienoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies (11Z,14Z)-Ethyl icosa-11,14-dienoate (CAS 103213-62-3), a certified reference material (molecular formula C22H40O2, MW 336.55 g/mol) for analytical method development and quality control.
The molecular framework of (11Z,14Z)-Ethyl icosa-11,14-dienoate (C22H40O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
As a certified reference material (CRM), (11Z,14Z)-Ethyl icosa-11,14-dienoate 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.
