Used in organic synthesis as a protected nucleoside analog intermediate, particularly in the preparation of modified adenine derivatives for pharmaceutical and biochemical research. Its ethyl ester and acetyl-protected groups allow selective reactions at specific sites, making it valuable in the development of antiviral and anticancer agents. Commonly employed in the synthesis of nucleoside analogs that mimic natural nucleobases, helping to inhibit viral replication or modulate cellular processes. Also utilized in studies involving DNA/RNA chemistry due to its stability and reactivity profile.
