O-Proparagyl-N-Boc-ethanolamine is a propargyl-functionalized, Boc-protected ethanolamine used as a crosslinker and synthetic building block. It provides an alkyne handle for copper-catalyzed azide-alkyne cycloaddition (click chemistry) and a t-Boc-protected amine that can be removed under mild acidic conditions to expose a free amine for further derivatization.
- Alkyne handle for copper-catalyzed click chemistry enabling selective bioconjugation.
- Boc-protected amine stable during handling and removable under mild acidic conditions.
- Suitable as a crosslinker and synthetic intermediate in small-molecule and bioconjugation workflows.
- Manufacturer COA reports GC purity 95.07% (rounded: 95.1%).
- Recommended storage: pure form -20°C (up to 3 years) or 4°C (up to 2 years); in solvent -80°C (up to 6 months).
