trans-Methyl crotonate

CAS: 623-43-8

Trans-methyl crotonate (trans-Methyl crotonate) is a dimethyl fumarate that is used as an analytical reagent for the determination of fatty acids. This reagent is prepared by an asymmetric synthesis and has been shown to be a potential candidate for the treatment of infectious diseases because it inhibits cell growth in the presence of oxygen. The reaction mechanism is not yet fully understood, but it has been found to inhibit glycol ethers and esters, which may play a role in its anti-inflammatory activities. Trans-methyl crotonate has also been shown to have kinetic properties that are dependent on its structure.
