Medchemexpress LLC DBCO-NHS ester 2 250mg | 1384870-47-6 | 250 MG
DBCO-NHS ester 2 is a dibenzocyclooctyne-derived N-hydroxysuccinimide (NHS) ester used as an amine-reactive linker for copper-free click chemistry and antibody-drug conjugate synthesis. The activated NHS ester enables rapid conjugation to primary amines, while the DBCO moiety enables strain-promoted azide-alkyne cycloaddition (SPAAC) without copper catalysts.
- Amine-reactive NHS ester for efficient amide bond formation
- Enables strain-promoted azide-alkyne cycloaddition (SPAAC) for copper-free click chemistry
- High purity (99.69%) suitable for bioconjugation applications
- Molecular weight 430.45 Da; formula C25H22N2O5
- Powder form; store at -20°C for long-term stability
- Packaged as a 250 mg solid for laboratory use
