What is Pentane? It is an organic compound with the formula C5H12, that is an alkane with five carbon atoms. The term may refer to any of three structural isomers, or to a mixture of them: in the IUPAC nomenclature, however, pentane means exclusively the n-pentane isomer; the other two being called isopentane (methylbutane) and neopentane (dimethylpropane). Cyclopentane is not an isomer of pentane. Pentanes are components of some fuels and are employed as specialty solvents in the laboratory. Their properties are very similar to those of butanes and hexanes.

Consistent Quality: We provide only high-quality Pentane 95%, meeting the standards of ACS, ensuring reliable and consistent performance for all applications.

Glass Winchester Bottle: Available in 500ml, 1L and 2.5L pack sizes. Our Glass Winchester bottles can store chemicals that may be sensitive to light due to filtering potentially harmful UV rays. Bottles are durable, versatile and perfect for storing products in the chemical, pharmaceutical and cosmetic industries.

Frequent uses

Plastic production
Pentanes are some of the primary blowing agents used in the production of polystyrene foam and other foams. Usually, a mixture of n-, i-, and increasingly cyclopentane is used for this purpose.

Fuels
Acid-catalysed isomerisation gives isopentane, which is used in producing high-octane fuels.

Power stations
Because of their low boiling points, low cost, and relative safety, pentanes are used as a working medium in geothermal power stations and organic Rankine cycles. It is also used in some blended refrigerants.

Solvents
Pentanes are relatively inexpensive and are the most volatile liquid alkanes at room temperature, so they are often used in the laboratory as solvents that can be conveniently and rapidly evaporated. However, because of their nonpolarity and lack of functionality, they dissolve only nonpolar and alkyl-rich compounds. Pentanes are miscible with most common nonpolar solvents such as chlorocarbons, aromatics, and ethers.
