Product profile
5'-Azido-5'-deoxy-2'-O-methyl-5-methyluridine is classified as 2'-o-me nucleosides (Formula C11H15N5O5; molecular weight 297.27).
5'-Azido-5'-deoxy-2'-O-methyl-5-methyluridine is useful as a bioorthogonal handle for post-synthetic conjugation to fluorophores, affinity tags, surfaces, peptides or other functional payloads.
For 5'-Azido-5'-deoxy-2'-O-methyl-5-methyluridine, 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.
- 2′-O-methyl groups are widely used to increase nuclease resistance and modulate hybridization behavior.
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.
- Excessive or poorly positioned substitution can reduce desired enzyme interactions or activity in some assay formats.
