Used primarily as an intermediate in organic synthesis, especially in the production of plasticizers, solvents, and fragrance compounds. It plays a role in the manufacture of caproic acid and other aldehyde derivatives used in flavors and perfumes due to its fruity odor. Also utilized in the synthesis of agrochemicals and pharmaceuticals where a six-carbon aldehyde chain is required. Its reactivity makes it suitable for condensation reactions, including aldol and oxo processes, contributing to the development of larger molecules in industrial chemistry.
