Opis

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.[1] It is reported to be the degradation product of 2,4,5-trichlorophenoxyacetic acid[2][3] and γ-hexachlorocyclohexane.[4]
