Chemical Information
FooDB Name2-Methylphenol
Descriptiono-Cresol, also known as ortho-cresol or 2-hydroxytoluene, belongs to the class of organic compounds known as ortho cresols. These are organic compounds containing an ortho-cresol moiety, which consists of a benzene bearing one hydroxyl group at ring positions 1 and 2, respectively. o-Cresol is an extremely weak basic (essentially neutral) compound (based on its pKa). o-Cresol exists in all living species, ranging from bacteria to humans. o-Cresol is a medicinal, musty, and phenolic tasting compound. o-Cresol is found, on average, in the highest concentration in peppermints. o-Cresol has also been detected, but not quantified in, several different foods, such as arabica coffee, green bell peppers, sour cherries, orange bell peppers, and asparagus. This could make O-cresol a potential biomarker for the consumption of these foods. o-Cresol is a potentially toxic compound. o-Cresol has been found to be associated with the diseases such as cresol poisoning ibs; also O-cresol has been linked to the inborn metabolic disorders including celiac disease.
