| | 2,5-DICHLOROHYDROQUINONE Usage And Synthesis |
| Chemical Properties | almost white to pink-brown crystalline powder | | Definition | ChEBI: A dichlorohydroquinone that is hydroquinone substituted by chloro groups at positions 2 and 5 respectively. | | General Description | 2,5-Dichlorohydroquinone (2,5-DCHQ) is a hydroquinone derivative that can be synthesized by reducing 2,5-dichloroquinone using sodium dithionite (Na2S2O4). The kinetics of the reaction of 2,5-DCHQ and N-phenyl-1,4-benzoquinonemonoimine has been studied. The transformation of 2,5-DCHQ to 2-chloromaleylacetate using PcpA (Pcp = pentachlorophenol) protein, isolated from Escherichia coli has been investigated. It is reported to be the degradation product of 2,4,5-trichlorophenoxyacetic acid and γ-hexachlorocyclohexane. |
