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.
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.
