Verwenden
2,6-Dichloro-1,4-benzoquinone is the suitable reagent used to in a study to evaluate the diffusion coefficients (D) for a family of quinones, nitroaromatics, ferrocenes and aromatic hydrocarbon compounds, in acetonitrile by single potential step chronoamperometry.1 It may be used in the preparation of 2,3,5-Trichloro-1,4-dihydroquinone, 2,3,5-trichloro-1,4-benzoquinone and 2,6-Dichloro-1,4-dihydroquinone.
Definition
ChEBI: 2,6-dichlorobenzoquinone is a member of the class of 1,4-benzoquinones that is p-benzoquinone in which the hydrogens at positions 2 and 6 have been replaced by chlorines. A highly toxic and carcinogenic disinfection by-product found in drinking water. It has a role as a carcinogenic agent and a poison. It is a member of 1,4-benzoquinones and an organochlorine compound.
Allgemeine Beschreibung
2,6-Dichloro-1,4-benzoquinone (DCBQ, 2,6-DCBQ) is a halobenzoquinone. Halobenzoquinones are disinfection byproducts (DBPs) found in drinking water. They are capable of producing reactive oxygen species and causing oxidative damage to proteins and DNA in T24 human bladder carcinoma cells. UV-induced transformation of DCBQ in drinking water has been reported. Detection of DCBQ in drinking water by liquid chromatography-ESI tandem mass spectrometry has been reported.
läuterung methode
Recrystallise the quinone from pet ether (b 60-70o). It sublimes at 41o/17.6. [Carlson & Miller J Am Chem Soc 107 479 1985, Beilstein 7 II 580. 7 III 3376.]
