Used as a key intermediate in organic synthesis, particularly in the production of pharmaceuticals and agrochemicals. It serves as a building block for the synthesis of various compounds, including barbiturates and other heterocyclic structures. Its reactivity allows for the introduction of dimethylmalonate units into more complex molecules, making it valuable in the development of active pharmaceutical ingredients. Additionally, it is employed in the manufacture of dyes, resins, and plasticizers, where its chemical properties enhance the performance and stability of the final products.
