Used in the synthesis of pyrethroid insecticides, which are widely applied in agriculture and household pest control due to their high efficiency and low mammalian toxicity. Also serves as an intermediate in the production of pharmaceuticals and agrochemicals. Frequently employed in fragrance and flavor formulations for perfumes, cosmetics, and food products, contributing fruity notes such as apple, peach, or green accents. Additionally, it acts as a building block in organic synthesis for creating more complex aldehydes and alcohols through reduction or condensation reactions.
