General description

2,4,5-Trichlorophenol (2,4,5-TCP) is employed as a raw material in the preparation of various biocides.[1]

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.[1][2]
  • 2,4,5-trichlorophenoxyacetic acid (2,4,5-T), a herbicide.[1][3]
  • 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.[4]

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

Disclaimer

“The product is not intended for use as a biocide under global biocide regulations, including but not limited to US EPA′s Federal Insecticide Fungicide and Rodenticide Act, European Biocidal Products Regulation, Canada’s Pest Management Regulatory Agency, Turkey’s Biocidal Products Regulation, Korea’s Consumer Chemical Products and Biocide Safety Management Act (K-BPR) and others."
