Ethoxymethylene malononitrile(CAT: R000967) is an organic intermediate with the formula C₅H₄N₂O, typically appearing as a pale yellow to light brown crystalline solid. It features a reactive ethoxymethylene group conjugated to a malononitrile moiety, giving it strong electrophilic properties. This compound is widely used in heterocyclic synthesis, particularly for constructing pyridines, quinolines, and related nitrogen-containing frameworks in pharmaceutical and agrochemical research. Its high reactivity toward nucleophiles makes it valuable in condensation and cyclization reactions.
