Chemical Structure
Description
cis-11,14,17-Eicosatrienoic Acid Methyl Ester (CAS 55682-88-7) is a high-purity analytical reference standard with the molecular formula C21H36O2 and a molecular weight of 320.51 g/mol.
The molecular framework of cis-11,14,17-Eicosatrienoic Acid Methyl Ester (C21H36O2) is characterized by a steroid core, 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), cis-11,14,17-Eicosatrienoic Acid Methyl Ester 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.
