Used primarily in organic synthesis to introduce the allyl group into molecules, it serves as a key reagent in the production of pharmaceuticals, agrochemicals, and specialty chemicals. It is also employed in the preparation of polymers and resins, where it acts as a cross-linking agent. Additionally, it finds application in the synthesis of flavor and fragrance compounds due to its ability to form allylic derivatives. In research, it is utilized for studying reaction mechanisms involving allylic substitution and addition reactions.
