Used as a key intermediate in the synthesis of agrochemicals and pharmaceuticals, particularly in the development of herbicides and plant growth regulators. Its structure allows for selective functionalization, making it valuable in creating active ingredients that target specific biological pathways in plants. It is also employed in the preparation of nicotinamide derivatives with potential bioactive properties. Due to its aldehyde group and halogen substitutions, it participates in condensation and coupling reactions, enabling the construction of complex heterocyclic systems in medicinal chemistry.
