Product profile
3'-Azido-3'-deoxy-5-fluorouridine is classified as 3'-azido-3'-deoxy-5-fluorouridine nucleoside (Formula C9H10FN5O5; molecular weight 287.20 g/mol).
3'-Azido-3'-deoxy-5-fluorouridine is useful as a bioorthogonal handle for post-synthetic conjugation to fluorophores, affinity tags, surfaces, peptides or other functional payloads.
For 3'-Azido-3'-deoxy-5-fluorouridine, copper-catalyzed, copper-free or inverse-electron-demand click conditions can affect sensitive oligonucleotides differently; residual metal, solvent and purification strategy should be controlled.

Product-specific evaluation notes
Potential advantages
- Click-compatible handles separate oligonucleotide synthesis from late-stage labeling, which helps screen multiple payloads from a common intermediate.
- Reactive handles make the product adaptable across dye-labeling, surface-coupling and ligand-conjugation workflows.
- 2′-fluoro motifs can improve nuclease resistance while preserving RNA-like geometry in many sequence contexts.
Method limitations
- Copper-catalyzed, copper-free or inverse-electron-demand click conditions can affect sensitive oligonucleotides differently; residual metal, solvent and purification strategy should be controlled.
- Functional handles may require orthogonal protection, pH control and rapid purification to avoid hydrolysis, oxidation or cross-reaction.
- Coupling, deprotection and biological performance remain sequence- and position-dependent.
