Used primarily as an intermediate in organic synthesis, especially in the production of pharmaceuticals and agrochemicals. It serves as a building block for heterocyclic compounds due to its reactive aldehyde and ketone functional groups. Commonly employed in the synthesis of pyrethroid insecticides, where it contributes to the formation of cyclopropane rings. Also utilized in the preparation of flavor and fragrance compounds, owing to its ability to form complex esters and acetals. Its alpha-keto aldehyde structure makes it valuable in condensation reactions and multistep synthetic pathways.
