Used primarily as an intermediate in organic synthesis, particularly in the production of fragrances and flavor compounds. Its aldehyde functionality and conjugated structure make it valuable in creating complex aroma chemicals. It serves in the synthesis of pyrethroids, which are widely used in insecticides due to their high potency and low mammalian toxicity. Also utilized in the preparation of specialty chemicals for agrochemicals and pharmaceuticals, where its reactivity allows for carbon-chain elongation and functional group transformations. Its role as a building block in Michael addition and aldol condensation reactions further enhances its utility in fine chemical manufacturing.
