Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of active pharmaceutical ingredients (APIs) involving pyridine derivatives. It serves in the development of agrochemicals, including certain herbicides and pesticides, due to its reactivity in substitution reactions. Also employed in research laboratories for the preparation of functionalized pyridines used in medicinal chemistry and material science. Its nitro and chloro groups allow for sequential functionalization, making it valuable in multi-step organic synthesis.
