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 hydrogenation, hydrolysis, and nucleophilic addition, enabling the construction of complex molecules. Commonly employed in the synthesis of active pharmaceutical ingredients (APIs) where the cyano group can be converted into amides, amines, or carboxylic acids. Also utilized in the development of specialty polymers and functional materials due to its reactive vinyl and nitrile moieties. Its liquid form and reactivity make it suitable for use in catalytic reactions and multistep synthetic routes.
