Used in biochemical research as a nucleotide analog to study enzyme mechanisms, particularly in RNA synthesis and carbohydrate metabolism. Its fluorinated sugar moiety allows for enhanced metabolic stability, making it suitable for probing glycosyltransferase activity and nucleoside diphosphate interactions. Also employed in the development of modified nucleotides for antiviral or anticancer agent design due to its ability to mimic natural substrates while resisting degradation.
