Used primarily as a blowing agent in the production of polyurethane foam insulation for refrigerators and buildings due to its low thermal conductivity and zero ozone depletion potential. Also serves as a solvent in some industrial processes and is a component in certain specialty fuels. Its low toxicity and favorable environmental profile make it preferable over chlorofluorocarbons and hydrochlorofluorocarbons in foam manufacturing. Additionally, cyclopentane is used in the synthesis of other organic compounds in research and development settings.
