4-Ethoxy-1,1,1-trifluoro-3-buten-2-one（Cat No.:R019120）is a fluorinated enone compound featuring a trifluoromethyl group at the 1-position, a ketone at the 2-position, a double bond between the 3- and 4-positions, and an ethoxy group on the terminal carbon. This clear to pale yellow liquid exhibits high reactivity due to the electron-withdrawing trifluoromethyl and carbonyl groups, making it a useful electrophile in organic synthesis. It is commonly employed in the preparation of heterocycles, pharmaceuticals, and agrochemicals, where its fluorinated structure enhances metabolic stability and bioavailability in target molecules.
