CAS 540-84-1: 2,2,4-Trimethylpentane
Description:2,2,4-Trimethylpentane, with the CAS number 540-84-1, is an organic compound classified as an alkane and is part of the branched-chain hydrocarbons. It has a molecular formula of C8H18, indicating it consists of eight carbon atoms and eighteen hydrogen atoms. This compound is characterized by its branched structure, which contributes to its relatively low boiling point compared to straight-chain alkanes of similar molecular weight. 2,2,4-Trimethylpentane is a colorless liquid at room temperature and is known for its high octane rating, making it a valuable component in gasoline formulations to improve engine performance and reduce knocking. It is insoluble in water but soluble in organic solvents, such as ethanol and ether. The compound is stable under normal conditions but can be flammable, necessitating proper handling and storage. Its uses extend beyond fuel additives to applications in the synthesis of other organic compounds and as a solvent in various chemical processes.
