Chemical Structure

Ethyl 11(E)-eicosenoate CAS 2692622-85-6 chemical structure

Description

As a certified reference material (CRM), Ethyl 11(E)-eicosenoate 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 11(E)-eicosenoate (CAS 2692622-85-6) is a high-purity analytical reference standard with the molecular formula C22H42O2 and a molecular weight of 338.57 g/mol.

Ethyl 11(E)-eicosenoate (C22H42O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
