2-Demethoxy-4-methoxy urapidil is a drug product that is used in the development of new drugs. It is a synthetic compound that is metabolized to form its natural metabolite, 2-demethoxyurapidil. This impurity standard has been shown to have anti-inflammatory effects and can be used as an API impurity for pharmacopoeia. 2DMO4MU has been shown to be useful in the study of metabolism and has been found to inhibit prostaglandin synthesis.
