Heptane is a colorless, flammable liquid that belongs to the alkane family of hydrocarbons. It has seven carbon atoms in its molecular structure, which gives it the chemical formula C7H16. Heptane is commonly found in gasoline and is used as a standard reference in measuring the octane rating of fuels. Its properties make it useful in laboratories and industrial applications. In addition to its role in fuel, heptane is also used as a solvent in various chemical reactions and processes. Due to its low boiling point, it evaporates quickly, making it ideal for applications where rapid drying is needed. However, safety precautions are essential when handling heptane, as it is highly flammable.
