Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antihypertensive drugs. It serves as a building block in the preparation of dihydropyridine derivatives, which are known for their calcium channel blocking activity. Also employed in the creation of agrochemicals and bioactive molecules due to its nitrogen-rich heterocyclic structure. Its amine functionality allows for easy modification, making it valuable in medicinal chemistry for structure-activity relationship studies.
