Product profile
3'-Deoxy-3'-fluoro-3-deazauridine is classified as modified nucleosides (Formula C10H12FNO5; molecular weight 245.21 g/mol).
3'-Deoxy-3'-fluoro-3-deazauridine is commonly assessed in siRNA, antisense and aptamer-style designs where ribose modification is used to tune stability and binding.
For 3'-Deoxy-3'-fluoro-3-deazauridine, coupling, deprotection and biological performance remain sequence- and position-dependent.
