Medchemexpress LLC Endo-BCN-NHS carbonate | 1426827-79-3 | MFCD19705416 | 99.5% | 291.30 g/mol | C15H17NO5 | 1 G
endo-BCN-NHS carbonate is an NHS carbonate reagent that installs a bicyclo[6.1.0]non-4-ynyl (BCN) strained alkyne onto primary amines, forming carbamate linkages. The BCN handle enables copper-free strain-promoted azide-alkyne cycloaddition (SPAAC) for efficient bioconjugation of proteins, peptides, and polymers, and is commonly used to functionalize biomolecules for hydrogel cross-linking and cell-encapsulation studies.
- Reacts with primary amines to form stable carbamate linkages.
- Provides a strained alkyne handle for copper-free SPAAC bioconjugation.
- Enables efficient functionalization of proteins, peptides, and polymers.
- Facilitates hydrogel cross-linking and cell encapsulation applications.
- Supplied as a high-purity solid suitable for research use.
