N3-PEG3-C2-NHS ester
Based on 1 Customer Validation
N3-PEG3-C2-NHS ester is a nonclaevable 3-unit PEG linker used in the synthesis of antibody-drug conjugates (ADCs). N3-PEG3-C2-NHS ester is a click chemistry reagent, it contains an Azide group and can undergo copper-catalyzed azide-alkyne cycloaddition reaction (CuAAc) with molecules containing Alkyne groups. It can also undergo strain-promoted alkyne-azide cycloaddition (SPAAC) reactions with molecules containing DBCO or BCN groups.
