1,3-Benzodioxole (1,2-methylenedioxybenzene) is an aromatic ring and a heterocyclic compound containing the methylenedioxy functional group. 1,3-Benzodioxole is synthesized from catechol with disubstituted halomethanes.[1][2] 1,3-Benzodioxole is useful in gemological simulant detection. It is precursor for perfumes, insecticides, and pharmaceuticals.
