Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of antihypertensive drugs and other biologically active compounds. It serves as a building block in agrochemicals for developing herbicides and insecticides due to its reactive nitrile and chloro groups. Also employed in the preparation of dyes and functionalized pyridine derivatives used in materials science and coordination chemistry. Its versatility in cross-coupling reactions makes it valuable in research and development of new organic molecules.
