1,2,3-Trichlorobenzene is an organochlorine compound with the chemical formula C6H3Cl3. [1] [2] This is one of three isomers of trichlorobenzene; the two others are 1,2,4-Trichlorobenzene and 1,3,5-Trichlorobenzene.
1,2,3-Trichlorobenzene can be prepared via dehydrohalogenation of hexachlorocyclohexane. Also, 1,3,5-trichlorobenzene is formed as a byproduct. Small amounts of 1,2,3-trichlorobenzene can also be produced while chlorinating benzene with iron(III) chloride as a catalyst. [3]
The compound forms white crystals with a faint aromatic odor. It is combustible [4] and poorly soluble in water. [5] The substance is irritating to eyes and the respiratory tract.
1,2,3-Trichlorobenzene is used as a herbicide. [5] [6] Also as a solvent for high-melting products, as a coolant in electrical installations and glass tempering. [7]
