Widely used as an intermediate in the synthesis of agrochemicals, particularly herbicides and insecticides. Its reactive chlorine groups allow for easy functionalization, making it valuable in building complex molecules. It is also employed in the production of dyes and pharmaceuticals where chlorinated aromatic scaffolds are needed. Due to its alkylating properties, it serves in the development of specialty chemicals, including polymer modifiers and biocides. Careful handling is required due to its lachrymatory and corrosive nature.
