Used as a key intermediate in organic synthesis, particularly in the production of pharmaceuticals and agrochemicals. It plays a crucial role in the formation of amides and esters through reactions with amines and alcohols, respectively. Its nitro and acyl chloride groups make it highly reactive, enabling its use in the development of complex molecules. Commonly applied in the synthesis of dyes, pigments, and active pharmaceutical ingredients (APIs) due to its ability to introduce functional groups into aromatic systems. Also utilized in research laboratories for studying reaction mechanisms and developing new synthetic pathways.
