2,4,5-Trichlorophenoxyacetic acid (also known as 2,4,5-T ), a synthetic auxin, is a chlorophenoxy acetic acid herbicide used to defoliate broad-leafed plants. It was developed in the late 1940s, synthesized by reaction of 2,4,5-Trichlorophenol and chloroacetic acid. It was widely used in the agricultural industry until being phased out ...
2,4,5-Trichlorophenol (TCP) is an organochloride with the molecular formula C 6 H 3 Cl 3 O.It has been used as a fungicide and herbicide. [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 of 2,3,7,8-Tetrachlorodibenzodioxin (TCDD, commonly ...
A trichlorophenol is any organochloride of phenol that contains three covalently bonded chlorine atoms. Trichlorophenols are produced by electrophilic halogenation of phenol with chlorine. [ 1] Different isomers of trichlorophenol exist according to which ring positions on the phenol contain chlorine atoms. 2,4,6-Trichlorophenol, for example ...

Hexachlorophene. Hexachlorophene, also known as Nabac, is an organochlorine compound that was once widely used as a disinfectant. The compound occurs as a white odorless solid, although commercial samples can be off-white and possess a slightly phenolic odor. It is insoluble in water but dissolves in acetone, ethanol, diethyl ether, and chloroform.
The accident occurred in the chemical plant's Building B. The chemical 2,4,5-trichlorophenol (2) was being produced there from 1,2,4,5-tetrachlorobenzene (1) by the nucleophilic aromatic substitution reaction with sodium hydroxide. The 2,4,5-trichlorophenol was intended as an intermediate for hexachlorophene. [4]
2,4,6-Trichlorophenol, also known as TCP, phenaclor, Dowicide 2S, Dowcide 2S, omal, is a chlorinated phenol that has been used as a fungicide, herbicide, insecticide, antiseptic, [ 3] defoliant, and glue preservative. [ 4] It is a clear to yellowish crystalline solid with a strong, phenolic odor. It decomposes on heating to produce toxic and ...
