Diethyl Maleate is an important industrial chemical and versatile intermediate primarily used in organic synthesis, polymerization processes, and specialty chemical formulations. Produced through the esterification of maleic acid with ethanol, it is characterized by its reactive double bonds that make it a valuable co-monomer in producing advanced resins, coatings, and adhesives. Its excellent reactivity and solubility in various organic solvents enable its wide application across multiple industries.
