Medchemexpress LLC DBCO-NHS ester 2 500mg | 1384870-47-6 | 430.45 | C25H22N2O5 | 500 MG
DBCO-NHS ester 2 is a dibenzylcyclooctyne (DBCO)-derived N-hydroxysuccinimide (NHS) ester used as an amine-reactive linker for bioconjugation and antibody-drug conjugate synthesis. The reagent enables copper-free click chemistry via strain-promoted alkyne-azide cycloaddition (SPAAC) and is supplied as a powder for laboratory use.
- Enables strain-promoted alkyne-azide cycloaddition (SPAAC) for copper-free click chemistry.
- Amine-reactive NHS ester for efficient labeling of proteins, peptides, and small molecules.
- Appropriate for antibody-drug conjugate (ADC) linker synthesis and general bioconjugation.
- High reported purity in product documentation.
- Powder form with long-term storage at -20°C; soluble in DMSO (≈14.29 mg/mL) with ultrasonic assistance.
