Used as an intermediate in organic synthesis, particularly in the preparation of pyrazole and pyrrole derivatives, which are important structures in pharmaceuticals and agrochemicals. It participates in condensation reactions to form heterocyclic compounds due to the reactivity of its ester groups. Commonly employed in the synthesis of active pharmaceutical ingredients where a triester functionality acts as a building block for ring formation. Also utilized in the development of specialty chemicals requiring multifunctional ester precursors.
