Used as an intermediate in organic synthesis, particularly in the pharmaceutical industry for the development of active pharmaceutical ingredients (APIs). It plays a role in the creation of complex molecules due to its reactive vinyl and carboxylate groups. Commonly employed in the preparation of pyrrolidine derivatives, which are key structures in various drugs targeting neurological and cardiovascular diseases. Its stability and reactivity make it suitable for use in multi-step synthetic processes, including cyclization and functional group transformations.
