benzyl-peg4-acid

Benzyl-PEG4-acid is a PEG-based linker for PROTACs which joins two essential ligands, crucial for forming PROTAC molecules. This linker enables selective protein degradation by leveraging the ubiquitin-proteasome system within cells.

Benzyloxy carbonyl-PEG4-acid is a linker with a benzyl protecting group and a carboxylic acid. The carboxylic acid can undergo reactions with primary amines with the help of activators (EDC or HATU). The benzyl protecting group can be removed via hydrogenolysis.
