Applications
Ethyl hydrogen malonate is used as a reactant for the preparation of tetramic acids through Dieckmann ring closure and organocatalytic decarboxylative Doebner-Knoevenagel reactions. It is involved in the acylation reactions and Knoevenagel condensation with aldehydes. It is also used in the preparation of gamma-lactones from olefins by intermolecular carbolactonization in presence of Mn(III) acetate as a catalyst.

Solubility
Miscible with water, chloroform and other solvents.

Notes
Incompatible with strong oxidizing agents.
