Used as a key intermediate in organic synthesis, particularly in the production of pharmaceuticals and agrochemicals. Its cyano and ester functional groups allow for versatile chemical transformations, such as hydrolysis, reduction, and nucleophilic addition reactions. Commonly employed in the synthesis of active pharmaceutical ingredients (APIs) where it contributes to building complex molecular structures. Also utilized in polymer chemistry as a monomer or modifier to introduce specific functional properties into copolymers. Its reactivity makes it valuable in creating specialty chemicals, including dyes and functional materials.
