2-[2-[2-[2-[2-[2-(Benzyloxy)ethoxy]ethoxy]ethoxy]ethoxy]ethoxy]ethanol

Benzyl-PEG7-alcohol is a PEG chain containing a benzyl protecing group and a primary alcohol group. The benzyl is an alcohol protecting group and can be removed via hydrogenolysis. The alcohol group can react to further derivatize the compound. The hydrophilic PEG chains increase the water solubility of the compound in aqueous media. Longer PEG chains have better water solubility properties relative to shorter PEG chains.

BnO-PEG6-OH is a non-cleavable 6 unit PEG ADC linker used in the synthesis of antibody-drug conjugates (ADCs). BnO-PEG6-OH is also a PEG-based PROTAC linker can be used in the synthesis of PROTACs[1][2].

BnO-PEG6-OH is a non-cleavable ADC linker containing 6-unit PEG, which can be used to synthesize antibody drug conjugates (ADC). It is also a PROTAC linker, belonging to the PEG class, which can be used to synthesize PROTAC molecules.
