Guaiacol
Guaiacol (/ˈɡwaɪəkɒl/) is a naturally occurring organic compound with the formula C7H8O2. It is usually derived from guaiacum or wood creosote. Samples darken upon exposure to air and light. Guaiacol is present in wood smoke, resulting from the pyrolysis of lignin. The compound contributes to the flavor of many substances such as whisky and roasted coffee.
