Product profile
3'-beta-Azido-3'-deoxythymidine is classified as amino-modified nucleosides (Formula C10H13N5O4; molecular weight 267.24 g/mol).
3'-beta-Azido-3'-deoxythymidine is useful as a bioorthogonal handle for post-synthetic conjugation to fluorophores, affinity tags, surfaces, peptides or other functional payloads.
For 3'-beta-Azido-3'-deoxythymidine, 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.
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.
