Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. Its conjugated nitrile and carboxylic acid functionalities make it suitable for carbon-chain extension reactions and cyclization processes. Commonly employed in the development of α,β-unsaturated carbonyl systems, it participates in Michael additions and Diels-Alder reactions. Also utilized in the synthesis of specialty monomers for functional polymers due to its reactive double bond and polar groups.
