Used as a key intermediate in the synthesis of agrochemicals, particularly herbicides and plant growth regulators. Its structure supports the development of compounds with selective activity against broadleaf weeds. Also employed in the preparation of pharmaceuticals where nicotinic acid derivatives play a role in bioactive molecule design. Commonly utilized in research for constructing complex heterocyclic systems due to its reactive functional groups and halogen positions, which allow for further chemical modifications such as cross-coupling reactions.
