Chemical Structure

(Z,Z)-5,11-Eicosadienoic Acid CAS 70363-48-3 chemical structure

Description

As a certified reference material (CRM), (Z,Z)-5,11-Eicosadienoic Acid 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.

(Z,Z)-5,11-Eicosadienoic Acid (CAS 70363-48-3) is a high-purity analytical reference standard with the molecular formula C20H36O2 and a molecular weight of 308.50 g/mol.

Structurally, (Z,Z)-5,11-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 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.
