Used in the synthesis of pharmaceuticals, particularly as an intermediate in the production of antihypertensive drugs and other biologically active compounds. It serves as a building block in agrochemicals for developing herbicides and pesticides due to its ability to modify biological activity in target organisms. Also employed in the preparation of ligands for catalysis and in the development of functional materials such as sensors and electronic chemicals. Its reactivity allows for easy substitution of the chlorine atom, making it valuable in various cross-coupling reactions in research and industrial settings.
