General description

n-Hexane, a straight-chain alkane, is a colorless liquid with a distinct hydrocarbon-like odor. It has a boiling point of 69°C (156°F) and is characterized by its high volatility and flammability. As a non-polar solvent, n-hexane is widely used in industrial applications and in laboratories for various chemical processes.
