Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of antihypertensive drugs and other biologically active compounds. It plays a key role in the development of agrochemicals, including herbicides and insecticides, due to its ability to form stable heterocyclic structures. Also utilized in the manufacture of dyes and functional materials where nitrogen-containing aromatic systems are required. Its amino and chloro functional groups allow for easy modification in multi-step organic syntheses.
