3,4-Methylenedioxyphenylpropan-2-one or piperonyl methyl ketone (MDP2P or PMK) is a chemical compound consisting of a phenylacetone moiety substituted with a methylenedioxy functional group. It is commonly synthesized from either safrole ((which, for comparison, is 3-[3,4-(methylenedioxy)phenyl]-2-propene) or its isomer isosafrole via oxidation using the Wacker oxidation or peroxyacid oxidation methods. MDP2P is unstable at room temperature and must be kept in the freezer in order to be preserved properly.
