Chemical Structure

ethyl (5Z,11Z)-icosa-5,11-dienoate CAS 1187888-75-0 chemical structure

Description

As a certified reference material (CRM), ethyl (5Z,11Z)-icosa-5,11-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.

ethyl (5Z,11Z)-icosa-5,11-dienoate (CAS 1187888-75-0), molecular formula C22H40O2 and molecular weight 336.55 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of ethyl (5Z,11Z)-icosa-5,11-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 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.
