Ethyl acetoacetate sodium salt is an organic compound typically appearing as a white to yellow to beige solid. It is used as a precursor or additive in the fabrication of functional organic-inorganic hybrid materials. It is also employed in the synthesis of advanced electrode materials, such as metal oxide nanoparticles, by acting as a stabilizer or precursor in solution-phase reactions. Its applications extend to areas like fuel cells, batteries, and supercapacitors, where it can play a role in the preparation of complex materials and doping processes.

Ethyl acetoacetate sodium salt can be used as:

• A chelating agent or ligand precursor to form metal-organic frameworks (MOFs) and coordination polymers, which are important in catalysis, sensors, and energy storage materials.
• A stabilizer or precursor in solution-phase reactions to produce metal oxide nanoparticles, which serve as advanced electrode materials in batteries, supercapacitors, and fuel cells.
• A β-keto ester component in the synthesis of complex heterocyclic structures, which are of significant interest in medicinal chemistry.
