Chemical Information
FooDB Name2-Methoxyphenol
DescriptionGuaiacol, also known as O-methoxyphenol or 2-hydroxyanisole, belongs to the class of organic compounds known as methoxyphenols. Methoxyphenols are compounds containing a methoxy group attached to the benzene ring of a phenol moiety. Guaiacol is an extremely weak basic (essentially neutral) compound (based on its pKa). Guaiacol exists in all living species, ranging from bacteria to humans. Guaiacol is a sweet, medicinal, and phenolic tasting compound. Guaiacol is found, on average, in the highest concentration within a few different foods, such as sesames, coffee, and white wines and in a lower concentration in peppermints. Guaiacol has also been detected, but not quantified in, several different foods, such as white mustards, peppers, red bell peppers, cherry tomato, and turmerics. This could make guaiacol a potential biomarker for the consumption of these foods. Guaiacol is a potentially toxic compound.
