Isoheptane

Isoheptane is a straight-chain alkane with the chemical formula C7H16. It is an isomer of heptane, meaning it has the same molecular formula but a different structural arrangement. Isoheptane is a colorless, flammable liquid at room temperature and is commonly used as a solvent in various industrial applications. It is also a component in some fuels, particularly in aviation fuel blends. Due to its high octane rating, isoheptane is used to improve the performance of gasoline by increasing its resistance to engine knocking. In the laboratory, isoheptane is often used as a solvent in chromatography and as a standard in gas chromatography. Its physical properties, such as boiling point (98.4°C) and melting point (-138°C), make it suitable for a wide range of applications. However, like other hydrocarbons, isoheptane is environmentally persistent and can have adverse effects on aquatic life, making its use and disposal subject to environmental regulations.
