This chemical, also known as DDD or TDE, was widely used in the past as an insecticide, particularly for controlling agricultural pests due to its high efficacy against various insect species. It was also employed in public health applications to manage disease vectors such as mosquitoes and flies. However, its use has been restricted or banned in many countries owing to significant environmental and human health risks, including bioaccumulation in the food chain and long-term adverse effects on ecosystems. Additionally, it serves as an intermediate in the synthesis of more complex organic compounds, particularly in pesticide production, and is studied in environmental chemistry for the degradation and persistence of chlorinated organic compounds.
