Descrição geral

Tetrachlorocatechol is a metabolite of pentachlorophenol. Acute toxicity of tetrachlorocatechol has been investigated in male and female mice.

Aplicação

Tetrachlorocatechol was used to investigate the inhibition of various ureases by halogenated benzo- and naphthoquinones, potent inhibitors of pure ureases from Bacillus pasteurii and Canavalia ensiformis. It may be used to prepare the copper(II) complexes of the potentially tripodal N,N,O ligand 3,3-bis(1-methylimidazol-2-yl)propionate (L1) and its conjugate acid HL1.

A novel photocatalysis material, F-Si-comodified TiO(2) (FST) powder, was synthesized by ultrasound-assisted hydrolysis. The prepared material was characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and UV-visible absorption spectroscopy, respectively. XRD analysis indicated that the phase of FST was

Pentachlorophenol (PCP) is used in industrial and domestic applications, including as a biocide and a wood preservative. Metabolism of PCP undergoes oxidative dechlorination, forming tetrachlorocatechol (TCC) and tetrachlorohydroquinone (TCHQ). Both sodium azide (NaN(3)) and TCC appear naturally in soil. None

Polyhalogenated benzo- and naphthoquinones were found to be potent inhibitors of pure ureases from Bacillus pasteurii and Canavalia ensiformis. They also inhibited ureases in whole cells of Helicobacter pylori, Klebsiella oxytoca and Proteus mirabilis. Inhibition was non-competitive with K(i) values
