Description and Uses
Trichlorobenzenes (TCBs) are synthetic chemicals that occur in three different isomeric forms. The three chlorinated cyclic aromatic isomers are 1,2,3-trichlorobenzene (1,2,3-TCB), 1,2,4-trichlorobenzene (1,2,4-TCB), and 1,3,5-trichlorobenzene (1,3,5-TCB). 1,2,4-TCB is one of the 188 chemicals designated as a hazardous air pollutant under the Clean Air Act.
1,3,5-Trichlorobenzene is used for someof these applications plus as a termite preparation and insecticide. These compounds are found as unintended by-products of the manufacture of the mono- and dichlorobenzenes.
