Metabolite Identification
Common Name3-Methylpentane
Description3-Methylpentane belongs to the class of organic compounds known as branched alkanes. These are acyclic branched hydrocarbons having the general formula CnH2n+2. These solvents are also used as cleaning agents in the printing, textile, furniture, and shoemaking industries. Breathing large amounts of hexane causes numbness in the feet and hands, followed by muscle weakness in the feet and lower legs. 3-Methylpentane is possibly neutral. 3-Methylpentane is a potentially toxic compound. Inhalation of high concentrations produces first a state of mild euphoria, followed by somnolence with headaches and nausea.
