3'-Azido-2',3'-dideoxy-5-hydroxyuridine

Product-specific evaluation notes

Potential advantages

• Fluorescent labels enable non-radioactive detection and can reduce downstream staining or secondary-label steps.
• 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.
• Dideoxy analogs provide clear extension-stop behavior when accepted by a polymerase.

Method limitations

• Dye-labeled nucleotides or amidites are bulkier than native monomers; incorporation efficiency, label density, photobleaching and light exposure should be controlled.
• 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.
• Polymerase acceptance varies; absence of a 3′-OH prevents further extension after incorporation.
