Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of bioactive molecules and drug candidates. Its rigid bicyclic structure and presence of two nitrogen atoms make it valuable for constructing nitrogen-containing heterocycles, which are common in medicinal chemistry. Frequently employed in the preparation of kinase inhibitors and other targeted therapies due to its ability to enhance binding selectivity and metabolic stability. Also utilized in the design of peptidomimetics and as a building block in combinatorial chemistry for high-throughput screening libraries.
