Ethyl linolelaidate (CAS 6114-21-2)

Ethyl linolelaidate, with the CAS number 6114-21-2, is an ester formed from the transesterification of linolelaidic acid (the trans isomer of linoleic acid) with ethanol. This chemical modification results in an ester that is part of a broader class of fatty acid ethyl esters, commonly utilized in research for their distinct physical and chemical properties compared to their acid counterparts. Specifically, ethyl linolelaidate′s molecular structure includes trans double bonds, which impart different melting and crystallization behaviors compared to the cis forms found in naturally occurring unsaturated fatty acids. In research settings, ethyl linolelaidate is particularly valuable for studying the effects of trans fats on lipid behavior in simulated environments. Due to its trans configuration, it serves as a model compound for investigating the impact of geometric isomerism on lipid packing, fluidity, and interactions within membranes. These studies are crucial for understanding the biophysical properties of trans fats at a molecular level. Additionally, ethyl linolelaidate is used in the synthesis of lipid-based materials, where its stability and melting properties are advantageous. It also finds utility in the study of lipid oxidation processes, where the presence of trans bonds can influence the kinetics and products of oxidation reactions, thereby providing insights into the stability and degradation mechanisms of trans fatty esters under various conditions.
