Used as a key intermediate in the synthesis of agrochemicals, particularly insecticides such as neonicotinoids, herbicides, and plant growth regulators. Its structure supports the development of compounds with selective activity in crop protection. Also employed in the preparation of pharmaceuticals, where it acts as a building block for heterocyclic molecules with biological activity, especially those targeting the nervous system. Commonly utilized in research for developing new nicotinic acid derivatives with potential therapeutic or agricultural applications.
