Used in pharmaceutical research as a chiral building block for synthesizing fluorinated nucleoside analogs. Its bromo and fluoro substituents allow selective cross-coupling reactions and structural modifications, making it valuable in developing antiviral and anticancer agents. The presence of ester groups enables controlled hydrolysis or enzymatic cleavage, useful in prodrug design. Commonly employed in structure-activity relationship (SAR) studies to optimize metabolic stability and bioavailability of nucleoside derivatives.
