Used primarily as an intermediate in the production of other chemicals, including pesticides, disinfectants, and wood preservatives. It serves as a key building block in synthesizing trichlorophenyl ethers and other chlorinated compounds used in agricultural and industrial applications. Also found in some antimicrobial formulations due to its biocidal properties, though its use in consumer products is limited due to toxicity and environmental concerns. Historically used in antifouling paints and as a fungicide, but many of these applications have been phased out or restricted in various regions.
