Used primarily as an intermediate in organic synthesis, especially in the production of fragrances and flavoring agents due to its fruity, floral odor profile. It serves as a building block for esters used in perfumery and cosmetics. Also employed in the synthesis of pharmaceuticals and agrochemicals where a branched-chain unsaturated acid moiety is required. Its reactivity allows for easy modification through esterification, reduction, or conjugation reactions, making it valuable in fine chemical manufacturing.
