Used primarily as an intermediate in organic synthesis, especially in the production of fine chemicals and pharmaceuticals. It participates in Michael addition reactions and can be transformed into various derivatives such as acids, alcohols, and amines. Commonly employed in the synthesis of fragrances and flavoring agents due to its reactive α,β-unsaturated aldehyde structure. Also utilized in the preparation of specialty polymers and agrochemicals where functionalized carbon chains are required. Its volatility and reactivity make it suitable for controlled reactions under inert conditions.
