Chemical Information
FooDB Name1,4-Dimethoxybenzene
Description1,4-Dimethoxybenzene, also known as dimethyl hydroquinone or p-methoxy-anisole, belongs to the class of organic compounds known as dimethoxybenzenes. These are organic aromatic compounds containing a monocyclic benzene moiety carrying exactly two methoxy groups. 1,4-Dimethoxybenzene is an extremely weak basic (essentially neutral) compound (based on its pKa). 1,4-Dimethoxybenzene is a sweet, bitter, and fennel tasting compound. 1,4-Dimethoxybenzene is found, on average, in the highest concentration within peppermints. This could make 1,4-dimethoxybenzene a potential biomarker for the consumption of these foods.
