Cycloheptane, synonym suberane, is a cycloalkane[citation needed] with the molecular formula C7H14.[1] It is a poorly water soluble organic liquid (melting point –12 deg C, solubility in water <30 mg /liter at 25 deg C),[1] and is used as a nonpolar solvent for the chemical industry and as an intermediate in the manufacture of chemicals and pharmaceutical drugs.[not verified in body] It can be prepared by Clemmensen reduction from cycloheptanone.[not verified in body] Cycloheptane vapour is irritating to the eyes and may cause respiratory depression if inhaled in large quantity.[not verified in body]
