Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of vasodilator drugs and calcium channel blockers. It serves as a building block in the development of active pharmaceutical ingredients due to its nicotinate ester structure, which is beneficial for modifying bioavailability and metabolic stability. Also employed in the preparation of agrochemicals and functionalized pyridine derivatives for crop protection agents. Its ester group allows for easy transformation in multi-step organic syntheses, making it valuable in medicinal chemistry research and process development.
