Medchemexpress LLC m-PEG7-4-nitrophenyl carbonate | 678150-56-6 | >97.1% | C20H31NO11 | 2 MG
m-PEG7-4-nitrophenyl carbonate is a PEG-based PROTAC linker used in the synthesis of PROTACs. PROTACs consist of two distinct ligands connected by a linker, where one targets an E3 ubiquitin ligase and the other targets a specific protein. This mechanism leverages the intracellular ubiquitin-proteasome system for selective degradation of target proteins. It appears as a colorless to light yellow liquid and is intended for research use only.
