Used primarily as an intermediate in the synthesis of pharmaceuticals and bioactive compounds. Its structure allows for selective functionalization, making it valuable in developing antimalarial and anticancer agents. Commonly employed in organic synthesis to introduce quinoline derivatives with specific electronic and steric properties. Also utilized in the preparation of dyes and fluorescent probes due to its aromatic nitro group and halogen reactivity. Serves as a building block in medicinal chemistry for constructing kinase inhibitors and antimicrobial agents.
