Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of nicotinamide-based drugs and kinase inhibitors. Commonly employed in the development of active pharmaceutical ingredients (APIs) due to its reactive aldehyde and chlorine functional groups, which allow for further chemical modifications. Also utilized in agrochemicals for the creation of herbicides and plant growth regulators. Its structure supports the formation of heterocyclic compounds, making it valuable in medicinal chemistry and drug discovery research.
