Applications
Ethyl potassium malonate is used as a competitive inhibitor of the enzyme succinate dehydrogenase. It acts as a precursor to produce (trimethylsilyl)ethyl malonate, which is utilized to prepare beta-ketoesters by acylation. Further, it reacts with aryl nitriles to prepare beta-amino acrylates in the presence of zinc chloride and a catalytic amount of Hünig′s base. In addition to this, it serves as an intermediate for the preparation of ethyl tert-butyl malonate.

Solubility
Soluble in water.

Notes
Hygroscopic. Incompatible with strong oxidizing agents.
