Used as an intermediate in the synthesis of biologically active compounds, particularly in the development of nucleoside analogs for pharmaceutical research. It serves as a building block in the preparation of modified purine derivatives that exhibit antiviral or anticancer properties. The tetrahydropyranyl group acts as a protective moiety, enabling selective reactions at other sites of the molecule during multi-step syntheses. Commonly employed in medicinal chemistry for optimizing drug candidates targeting kinases and other enzymes involved in cellular signaling pathways.
