Used primarily in organic synthesis, this chemical serves as a key intermediate in the production of dyes, pigments, and other aromatic compounds. It is also employed in the manufacture of agricultural chemicals, such as herbicides and insecticides, due to its reactivity with various organic molecules. In the pharmaceutical industry, it acts as a precursor for synthesizing certain drugs and active pharmaceutical ingredients. Additionally, it finds application in research laboratories for studying electrophilic aromatic substitution reactions. Proper handling and safety precautions are essential due to its toxic and potentially hazardous nature.
