Used in the synthesis of antiviral medications, particularly as an intermediate in the production of nucleoside analogs. It plays a key role in developing drugs that target RNA viruses due to its structural similarity to natural sugar moieties involved in viral replication. Its chiral centers allow for selective interactions with viral enzymes, enhancing drug efficacy. Also employed in research for novel therapeutics in neurology and oncology due to its ability to cross biological membranes and modulate cellular processes.
