Used primarily as an intermediate in the synthesis of other organic compounds, especially in the production of pesticides and pharmaceuticals. It serves as a building block in reactions where a trichloromethyl group is needed for further transformation. Its reactivity allows it to be incorporated into more complex molecules, making it valuable in industrial chemical processes. Due to its chlorinated structure, it can also act as a disinfectant or biocide in certain formulations, though such uses are limited due to environmental and stability concerns. Handling requires care, as it may decompose under heat or alkaline conditions, releasing harmful gases.
