Used primarily as an intermediate in organic synthesis, especially in the fragrance and flavor industry. It contributes to the creation of complex aroma compounds due to its strong, fruity, citrus-like odor. Commonly employed in perfumery to add green, fresh, or aldehydic notes to fragrance formulations. Also utilized in the synthesis of pharmaceuticals and agrochemicals where a functionalized carbon chain is required. Its α,β-unsaturated aldehyde structure makes it reactive in Michael addition and other conjugate addition reactions, enabling the construction of larger, more complex molecules.
