Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antiviral and antibacterial agents. Its structure allows for further functionalization, making it valuable in creating active pharmaceutical ingredients (APIs) with targeted biological activity. Commonly employed in heterocyclic chemistry to build complex nitrogen-containing ring systems. Also utilized in agrochemical research for developing novel pesticides due to its reactivity and ability to introduce chloro and nitro functionalities into larger molecules.
