Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) involving pyridine derivatives. It serves in agrochemical manufacturing for certain pesticides and herbicides due to its reactive chlorine and nitro groups. Also employed in research laboratories for building blocks in heterocyclic chemistry, enabling the creation of complex molecules through nucleophilic substitution and reduction reactions. Its structure allows for selective functionalization, making it valuable in fine chemical synthesis.
