Roles

  • metabolite
  • xenobiotic metabolite

How it is made

Chlorination of phenol in the presence of potassium tellurate as a catalyst, followed by separation of isomeric mixt, by product from production of pentachlorophenol by chlorination of phenol.

The tri- and tetrachlorophenols produced by direct chlorination of phenol have essentially similar chlorophenol contaminants, varying in concentrations with source and batch. (Tetrachlorophenols)
