Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of nicotinic acid derivatives and vitamin B3 (niacin) analogs. It serves as a building block in the development of drugs targeting neurological and cardiovascular conditions. Also employed in the preparation of agrochemicals, including herbicides and plant growth regulators, due to its reactive aldehyde group that facilitates further chemical modifications. Additionally, it finds use in the synthesis of specialty polymers and ligands for metal catalysts in organic reactions.
