Applications
Diethyl ethoxymethylenemalonate is used for synthesis of pyrido[3,2-e]pyrimido[1,2-c]pyrimidines. Initially, it was used to monitor lysine decarboxylase activity. It is useful in the determination of amino acids by precolumn derivatization by using reversed-phase high-performance liquid chromatography (HPLC). It plays an important role in the Gould-Jacobs reaction to prepare quinolines. For example, anile reacts with this reagent to give 4-hydroxyquinoline. It acts as an intermediate in the production of flumequine, which is a fluoroquinolone antibiotic.

Solubility
Miscible with chloroform, dichloromethane and methanol. Immiscible with water.

Notes
Incompatible with acids, bases, oxidizing agents and reducing agents.
