Metabolite Identification
Common Name4-Isopropyl-2-methoxy-1-methylbenzene
Description4-isopropyl-2-methoxy-1-methylbenzene, also known as O-methylcarvacrol, is a member of the class of compounds known as aromatic monoterpenoids. Aromatic monoterpenoids are monoterpenoids containing at least one aromatic ring. 4-isopropyl-2-methoxy-1-methylbenzene is practically insoluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). 4-isopropyl-2-methoxy-1-methylbenzene is a herbal, leafy, and spicy tasting compound and can be found in a number of food items such as common oregano, pepper (spice), winter savory, and summer savory, which makes 4-isopropyl-2-methoxy-1-methylbenzene a potential biomarker for the consumption of these food products.
