Used primarily as an intermediate in organic synthesis, especially in the production of pharmaceuticals and fine chemicals. Its conjugated structure makes it valuable in Michael addition reactions and Diels-Alder cycloadditions, enabling the construction of complex ring systems. Commonly employed in the development of active pharmaceutical ingredients (APIs), particularly in the synthesis of anti-inflammatory and antifungal agents. Also utilized in the preparation of specialty polymers and agrochemicals due to its reactivity and ability to form stable derivatives.
