CAS 111-65-9: Octane

Description: Octane, with the CAS number 111-65-9, is a straight-chain alkane with the molecular formula C8H18. It is a colorless, flammable liquid at room temperature, characterized by its relatively low viscosity and high volatility. Octane is primarily known for its role as a significant component of gasoline, where it serves as a measure of fuel quality, specifically in terms of its octane rating, which indicates its resistance to knocking during combustion. The substance has a boiling point around 125 degrees Celsius and a melting point of approximately -57 degrees Celsius. Octane is insoluble in water but soluble in organic solvents, making it useful in various industrial applications. Its combustion produces carbon dioxide and water, contributing to energy release, but it can also lead to the formation of pollutants if not burned efficiently. Due to its flammability, octane must be handled with care, following appropriate safety protocols to prevent fire hazards.
