Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of nicotinic acid derivatives and other biologically active compounds. It serves in the development of drugs targeting central nervous system disorders and metabolic diseases. Its ester groups allow for easy functionalization, making it valuable in medicinal chemistry for building complex heterocyclic structures. Also employed in agrochemicals to create herbicides and plant growth regulators due to its ability to modify biological activity in targeted molecules.
