Used primarily as an intermediate in the production of other chemicals, including dyes, pesticides, and disinfectants. It serves as a precursor in the synthesis of certain herbicides and acts as a biocide in industrial systems to control microbial growth. Also found in wood preservatives and antifouling agents due to its antimicrobial properties. Its derivatives are sometimes used in the manufacture of antioxidants and rubber chemicals. Due to toxicity and environmental persistence, its use is regulated in many countries.
