10-UNDECYNOIC ACID Chemical Properties,Usage,Production

Uses

10-Undecynoic Acid is a fatty acid used in the synthesis of copolyesters.

Uses

10-Undecynoic acid was employed as model compound to investigate the microwave assisted surface click reactions catalyzed with Cu(II)/sodium L-ascorbate.?
It may be used:

As a biochemical probe in an assay for the microsomal hydroxylation of lauric acid (LA), based on HPLC with flow-through radiochemical detection.
To form molecular layers by adsorbing on the fluorite surface.
In the supercritical hydrothermal synthesis of iron oxide nanoparticles.

Definition

ChEBI: 10-undecynoic acid is a medium-chain fatty acid.

General Description

10-Undecynoic acid (10- UDYA, UDY) is an acetylenic fatty acid. It is reported as highly selective irreversible inhibitor of hepatic ω- and ω-1-lauric acid hydroxylases. Enzyme catalyzed esterification of 10-undecynoic acid has been reported. UDY has been reported to be synthesized by the dehydrobromination of 10-undecenoic acid.
