Allyl ether is primarily used as an intermediate in organic synthesis, especially in the production of fine chemicals and pharmaceuticals. Its reactive allyl group allows it to participate in a variety of coupling and substitution reactions, making it valuable in constructing complex molecules. It is also employed in the synthesis of polymers and resins, where it acts as a modifier to improve flexibility and reactivity. In some cases, allyl ether derivatives are used as flavor and fragrance components due to their volatile nature. Additionally, it serves as a reagent in specialized industrial processes that require mild ether linkages with reactive potential.
