Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of vasodilator drugs and antihypertensive agents. It serves as a building block in the development of active pharmaceutical ingredients due to its heterocyclic structure, which enhances bioavailability and receptor binding. Also utilized in the preparation of functional materials and agrochemicals where sulfur-containing moieties improve stability and activity. Its amine group allows for easy derivatization, making it valuable in medicinal chemistry research and development.
