N-DBCO-N-bis(PEG2-C2-NHS ester) is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1]. N-DBCO-N-bis(PEG2-C2-NHS ester) is a click chemistry reagent, it contains a DBCO group that can undergo strain-promoted alkyne-azide cycloaddition (SPAAC) with molecules containing Azide groups.
Propargyl-O-C1-amido-PEG2-C2-NHS ester is a nonclaevable 2-unit PEG linker for antibody-agent-conjugation (ADC). Propargyl-O-C1-amido-PEG2-C2-NHS ester is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.
