Tosylate of Tetraethylene glycol monobenzyl ether

Liquid or Solid or Semi-solid

Benzyl-PEG4-Ots is a PEG-based PROTAC linker that can be used to synthesize PROTACs.

PROTAC contains two distinct ligands linked by a linker; one is a ligand for the E3 ubiquitin ligase and the other is a ligand for the target protein. PROTAC utilizes the intracellular ubiquitin-proteasome system to selectively degrade target proteins.
