Aplicaciones

Malonic acid is acts as a building block in organic synthesis. It is also useful as a precursor for polyesters and alkyd resins, which is used in coating applications, thereby protecting against UV light, corrosion and oxidation. It acts as a cross linker in the coating industry and surgical adhesive. It finds application in the production of specialty chemicals, flavors and fragrances, polymer cross linkers and pharmaceuticals.
