2-Prop-2-enoxybenzoic acid is used primarily as an intermediate in the synthesis of coumarin derivatives, which have applications in anticoagulant medications and fluorescent dyes. It also serves in the preparation of specialty polymers and resins due to its reactive carboxylic acid group and allyl ether moiety. Its structure allows for easy modification in organic synthesis, making it valuable in pharmaceutical research and development. Additionally, it finds use in the production of certain fragrances and flavoring agents where aromatic esters are required.
