Dodecyl azide (1-azidododecane) is a linear alkyl azide with a terminal azide (N3) group attached to a 12-carbon chain. It is used as an azide partner in copper-catalyzed and strain-promoted azide-alkyne cycloadditions (click chemistry) for labeling, conjugation, and synthetic transformations where a hydrophobic spacer is required. The compound has CAS 13733-78-3, formula C12H25N3, and molecular weight 211.35 g/mol.
- Terminal azide functional group for click chemistry.
- 12-carbon hydrophobic spacer suitable for conjugation and labeling.
- Compatible with alkynes, BCN, and DBCO reagents.
- Provided as a small-molecule research reagent for synthetic and bioconjugation use.
- Store solid at -20°C for long-term stability; store solutions at lower temperatures.
