Chemical Information
FooDB NamePentane
DescriptionPresent in hop oil Pentane is any or one of the organic compounds with the formula C5H12. This alkane is a component of some fuels and is employed as a specialty solvent in the laboratory. Its properties are very similar to those of butane and hexane. It exists in three structural isomers, the branched isomers are called isopentane and neopentane.; Pentane is one of the primary blowing agents used in the production of polystyrene foam. Pentane is found in kohlrabi, soy bean, and alcoholic beverages.
