Dec 30, 2025 Leave a message

n-pentane is a straight-chain alkane hydrocarbon with the chemical formula C5H12. It is a colorless, flammable liquid that is widely used as a solvent and in the production of gasoline.

 

Pentane contains 5 Carbon atoms and 12 Hydrogen atoms. The chemical formula of Pentane is C5H12. Three isomers are there for pentane, they are n-pentane, Isopentane, and Neo pentane. N-pentane is a straight-chain, Isopentane is branched like 2-methyl butane and Neo pentane is branched like 2,2-dimethyl propane. Another structure of pentane is Cyclopentane which is arranged like a ring. The most commonly used form on the market is n-pentane.

What are the applications of Pentane (N-Pentane)?

Synthetic rubber production: Pentane CAS 109-66-0 is a key monomer for manufacturing styrene-isoprene-styrene (SIS) and styrene-butadiene-styrene (SBS) block copolymers, used in tires, adhesives, and sealants.

 

Chemical intermediate: Converted into pentanols, pentanones, and other oxygenated organic compounds, which are used as solvents, plasticizers, and raw materials for pharmaceuticals.

 

Polymerization: Chemical N-Pentane is used in the production of low-molecular-weight polyolefins, which serve as lubricant additives and viscosity modifiers.

 

Fuel additive: Improves gasoline's octane rating and combustion efficiency; also used as a blending component for jet fuel.

 

Laboratory reagent: Utilized in organic synthesis to introduce pentyl groups into target molecules.
