Used primarily as an intermediate in the synthesis of agrochemicals and pharmaceuticals. It plays a key role in the production of certain herbicides and fungicides due to its ability to introduce halogenated benzoyl groups into active molecules. Its reactivity makes it valuable in forming amide and ester derivatives, especially in the development of crop protection agents. Also utilized in research settings for constructing complex organic molecules where selective halogen placement is required. Handling requires caution due to its moisture sensitivity and potential to release corrosive fumes.
