Bis-PEG9-NHSester（Cat No.:I014259） is a connecting bridge commonly used in the synthesis of PROTAC molecules. It belongs to the PEG (polyethylene glycol) class and the Alkyl/ether class of linkers. This compound enables the conjugation of small molecule ligands to target proteins for targeted protein degradation. Additionally, Bis-PEG9-NHSester can function as a cleavable linker in the synthesis of antibody-drug conjugates (ADCs), allowing for the selective delivery of cytotoxic drugs to specific targets for enhanced therapeutic efficacy.
