General description

2,4,5-Trichlorophenol (2,4,5-TCP) is employed as a raw material in the preparation of various biocides.

Application

2,4,5-trichlorophenol can be used as a starting material to synthesize:
  • Hexachlorophene, a fungicide, by the reaction with formaldehyde in the presence of concentrated H2SO4.
  • 2,4,5-trichlorophenoxyacetic acid (2,4,5-T), a herbicide.
  • N-Benzyl-2-(2,4,5-trichlorophenoxy)acetamide, which is used as an intermediate to prepare 4-benzyl-6,7-dichloro-2H-benzo[b][1,4]oxazin-3(4H)-one via Smiles rearrangement.

The product has been used to study its sorption onto montmorillonite based sorbents.

Trichlorophenols (TCPs) are organochlorine compounds which are ubiquitous in the environment and well known for their carcinogenic effects. However, little is known about their neurotoxicity in humans. Our goal was to examine the association between body burden of TCPs (ie
