Used as a key intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. It serves as a building block for introducing nitrile and bromine functionalities into more complex molecules. Commonly employed in the synthesis of heterocyclic compounds, which are important in drug development. Also utilized in the production of certain pesticides due to its reactivity in carbon-carbon bond formation. Its versatility makes it valuable in research laboratories for developing new bioactive compounds.
