| Hazard Information | Back Directory | [Description]
1,3-Benzodioxole, widely found in plant products, has shown potent antioxidant and antibacterial activities. It has recently been reported that 1,3-benzodioxole derivatives possess cytotoxic activity against several human tumor cell lines, including human colon carcinoma cells and multidrug-resistant nasopharyngeal carcinoma cells. No cytotoxic effects were noticed at a concentration of 10-4 M. | [Chemical Properties]
CLEAR COLOURLESS TO LIGHT YELLOW LIQUID | [Uses]
1,3-Benzodioxole is useful in gemological stimulant detection. It is also used as a precursor for perfumes, photo initiators, agrochemicals and pharmaceuticals. 1,3-benzodimine is an intermediate for the synthesis of the drugs oxolinic acid, cinoxacin and miloxacin. | [Application]
1,3-Benzodioxole belong to methylenedioxyphenyl (MDP) compounds that regulate cytochrome P 450-dependent drug oxidation, which is important in the process of eliminating drugs from the body. a hydrogen abstraction process can take place from the methylene-bridgea carbon of the benzodioxole compound and form a methylenedioxybenzene radical. It is therefore highly likely that 1,3-benzodioxole could serve as hydrogen donor for a CQ-based system initiating the photopolymerization of dental composite resin. In addition, 1,3-benzodioxole is an important organic intermediate (building block) to synthetize substituted methylenedioxybenzene products. | [Definition]
ChEBI: A benzodioxole consisting of a benzene ring substituted by a the methylenedioxy group. | [Production Methods]
1,3-Benzodioxole is a colorless liquid. This compound is prepared by the reaction of catechol and dihalomethanes, for example, by use of concentrated aqueous alkaline solution in the presence of tetraalkylammonium or phosphonium salts, sometimes in the presence of alkyl iodides. 1,3-Benzodioxole is an important intermediate in organic synthesis, especially for the preparation of alkaloids.
| [General Description]
Supersonic jet fluorescence spectra of 1,3-benzodioxole has been studied. The far-infrared spectrum of the vapour of 1,3-benzodioxole has been reported. The electronic absorption spectra and the laser-induced fluorescence spectra of supersonic-jet-cooled 1,3-benzodioxole molecules has been investigated. |
