CAS 109-66-0: Pentane

Description: Pentane is a straight-chain alkane with the molecular formula C5H12, characterized by its five carbon atoms connected by single bonds. It is a colorless, flammable liquid at room temperature, with a distinctive odor reminiscent of gasoline. Pentane is insoluble in water but soluble in organic solvents, making it useful in various applications, including as a solvent in laboratories and in the production of polystyrene. Its boiling point is relatively low, allowing it to evaporate quickly, which is a property exploited in certain industrial processes. Pentane exists in three isomeric forms: n-pentane (the straight-chain form), isopentane, and neopentane, each exhibiting slightly different physical properties. Due to its volatility, pentane is often used as a reference standard in gas chromatography. Additionally, it is a component of natural gas and is produced during the refining of crude oil. Safety precautions are necessary when handling pentane, as it poses fire and health hazards due to its flammability and potential to cause respiratory irritation.
