Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of nicotinic acid derivatives with potential antihypertensive and antiarrhythmic activities. It serves as a building block in medicinal chemistry for constructing pyridine-based drug candidates. Also employed in agrochemical research for developing novel pesticides and herbicides due to its reactive ester groups and halogen substitution, which allow further functionalization. Its structure supports efficient derivatization in multistep organic syntheses.
