'''1,3-Benzodioxole''' ('''1,2-methylenedioxybenzene''') is an ] with the formula C{{sub|6}}H{{sub|4}}O{{sub|2}}CH{{sub|2}}. The compound is classified as ] derivative and a ] containing the ] ]. It is a colorless liquid.

Although benzodioxole is not particularly important, many related compounds containing the methylenedioxyphenyl group are bioactive, and thus are found in pesticides and pharmaceuticals.<ref>Murray, M., "Mechanisms of inhibitory and regulatory effects of methylenedioxyphenyl compounds on cytochrome P450-dependent drug oxidation", Curr. Drug Metab. 2000, volume 1, 67-84. {{doi|10.2174/1389200003339270}}</ref>
