Used as an intermediate in organic synthesis, particularly in the pharmaceutical industry for constructing complex molecules. Its reactivity allows for the introduction of functionalized side chains in active pharmaceutical ingredients. Commonly employed in the preparation of heterocyclic compounds and as a building block in the synthesis of gamma-aminobutyric acid (GABA) analogs. Also utilized in the development of agrochemicals and specialty polymers due to its ability to undergo alkylation and condensation reactions.
