Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in the preparation of bioactive molecules due to its ability to form stable heterocyclic structures. Commonly employed in medicinal chemistry for structure-activity relationship studies targeting enzyme inhibition. Also utilized in agrochemical research for developing new active ingredients with pesticidal or herbicidal properties. Its reactivity allows for functionalization at multiple sites, making it valuable in combinatorial chemistry and drug discovery.
