Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of certain antihypertensive and antiviral drugs. It serves as a building block in agrochemicals for developing herbicides and insecticides due to its reactive amine and halogen groups. Also employed in the manufacture of dyes and functionalized polymers where nitrogen-containing heterocycles enhance material stability and performance. Its structure allows for easy modification in multi-step organic syntheses, making it valuable in research and development laboratories for creating novel bioactive compounds.
