Used as a protected intermediate in the synthesis of purine-based pharmaceuticals, particularly in the development of antiviral and anticancer agents. The Boc (tert-butoxycarbonyl) group provides stability during peptide or nucleoside assembly by preventing unwanted side reactions at the amine site. This compound is valuable in solid-phase synthesis and combinatorial chemistry, where selective deprotection allows stepwise construction of complex molecules. Commonly employed in the preparation of kinase inhibitors and nucleoside analogs due to its compatibility with various coupling and deprotection conditions.
