Used primarily as an intermediate in the synthesis of fine chemicals and specialty fragrances. Its conjugated aldehyde structure makes it valuable in condensation reactions for producing unsaturated compounds. Commonly employed in the fragrance industry to create fruity and floral aroma compounds due to its strong, pungent odor. Also utilized in the preparation of agrochemicals and pharmaceuticals where an α,β-unsaturated aldehyde moiety is required. Its reactivity allows for easy functionalization, making it useful in organic synthesis for building carbon chains and introducing aldehyde groups in complex molecules.
