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 the development of nicotinic receptor ligands and agrochemicals due to its pyridine core and reactive functional groups. Its chloro and hydroxyl groups allow for further chemical modifications, making it valuable in medicinal chemistry for creating diverse compound libraries. Also employed in the preparation of catalysts and functional materials where pyridine derivatives enhance catalytic activity or stability.
