Description générale

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

Application

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
