Used as an intermediate in organic synthesis, particularly in the production of pharmaceuticals and agrochemicals. It serves as a building block for the preparation of nitrogen-containing compounds such as amines, amino acids, and heterocyclic derivatives. Its nitrile and ester functional groups allow for versatile chemical transformations, including reduction, hydrolysis, and cyclization reactions. Commonly employed in the synthesis of active pharmaceutical ingredients (APIs) where a three-carbon spacer with functional handles is required. Also utilized in the development of specialty polymers and fine chemicals due to its reactivity and solubility properties.
