Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antiviral and anticancer agents. Its structure supports the creation of complex organic molecules by serving as a building block with enhanced bioavailability and metabolic stability. Commonly employed in medicinal chemistry for constructing nitrogen-containing heterocycles and functionalized amines. Also utilized in the preparation of novel kinase inhibitors and protease inhibitors due to its favorable reactivity and compatibility with various coupling reactions.
