Properties of m-isobutylphenol

3-Isobutylphenol (CAS number: 665-12-5) is an organic compound with the formula C10H14O. It is a colorless to pale yellow liquid at normal temperature and pressure, with a unique smell of phenolic compounds. Its molecular structure contains an isobutyl substituent located in the meta position of the benzene ring (I. e., 1,3-position). M-isobutyl phenol has a high boiling point and low solubility, and its solubility in water is limited, but it can be dissolved in many organic solvents such as ethanol, ether and benzene. It is chemically stable, but may undergo decomposition or other chemical reactions at high temperatures or exposure to strong acids and alkalis.
