2,4,5-Trichlorophenol (TCP) is anorganochloride with the molecularformulaC6H3Cl3O. It has been used as afungicide andherbicide.[2] Precursor chemical used in the production of 2,4,5-Trichlorophenoxyacetic acid (2,4,5-T) and hexachlorophene involves the intermediate production of 2,4,5-trichlorophenol (TCP) and the formation of2,3,7,8-Tetrachlorodibenzodioxin (TCDD, commonly referred to simply as dioxin) as an unwanted by-product. In the course of purifying the hexachlorophene, still bottom wastes were created with concentrated levels of TCP and dioxin.
