Used primarily as an intermediate in organic synthesis, this compound serves in the production of pharmaceuticals, agrochemicals, and specialty esters. Its reactive carboxylic acid and olefinic groups allow for derivatization into esters, amides, and other functionalized molecules. It is also employed in the preparation of polymer modifiers and fragrance components due to its ability to participate in addition and condensation reactions. Its structure supports the development of branched-chain analogs in medicinal chemistry.
