3-(Allyloxy)benzoic acid is primarily used in organic synthesis as a building block for creating more complex chemical compounds. It is often employed in the development of polymers and resins, where its allyl group enables it to participate in polymerization reactions, enhancing material properties like durability and flexibility. Additionally, it serves as an intermediate in the production of pharmaceuticals, contributing to the synthesis of active pharmaceutical ingredients (APIs) with potential therapeutic applications. Its benzoic acid moiety also makes it useful in the formulation of specialty chemicals, such as dyes and agrochemicals, where it can act as a functional group modifier.
