Iso-octane is a colorless, flammable liquid hydrocarbon that is commonly used as a reference fuel in the automotive industry. It is a component of gasoline and is known for its high octane rating, which helps prevent engine knocking. Iso-octane is part of the alkane family and has the chemical formula C8H18. In laboratory settings, iso-octane is often used in experiments to study combustion and fuel properties. Its stability and low reactivity make it an ideal standard for comparing the performance of other fuels. Additionally, iso-octane is utilized in the production of various chemicals and solvents.
