Chemical Structure

11-cis,14-cis-Eicosadienoic acid CAS 5598-38-9 chemical structure

Description

11-cis,14-cis-Eicosadienoic acid (CAS 5598-38-9) is a high-purity analytical reference standard with the molecular formula C20H36O2 and a molecular weight of 308.50 g/mol.

Structurally, 11-cis,14-cis-Eicosadienoic acid (C20H36O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 308.50 g/mol, it falls into the moderately-high-molecular-weight range. 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).

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.

CATO manufactures 11-cis,14-cis-Eicosadienoic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
