Used as an intermediate in the synthesis of antiviral medications, particularly in the production of guanosine nucleoside analogs. These analogs are designed to mimic natural nucleosides, allowing them to interfere with viral replication processes. The compound's stereochemistry and functional groups make it suitable for incorporation into larger molecules that target DNA or RNA viruses. It is especially valuable in the development of drugs aimed at treating herpes infections, hepatitis B, HIV, and other viral infections. Its acetylated form helps improve stability during the synthetic process, facilitating easier handling and higher yields in pharmaceutical manufacturing.
