Medchemexpress LLC m-PEG4-phosphonic acid | 1872433-62-9 | 99.36% | C9H21O7P | 50 MG
SDP

m-PEG4-phosphonic acid is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs. PROTACs contain two different ligands connected by a linker; one is a ligand for an E3 ubiquitin ligase and the other is for the target protein. PROTACs exploit the intracellular ubiquitin-proteasome system to selectively degrade target proteins.
