Guaiacol (/ˈɡwaɪəkɒl/) is an organic compound with the formula C₆H₄(OH)(OCH₃). It is a phenolic compound containing a methoxy functional group. Guaiacol appears as a viscous colorless oil, although aged or impure samples are often yellowish. It occurs widely in nature and is a common product of the pyrolysis of wood.^[3]
