2,4,5-三氯苯酚

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

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.
