Medchemexpress LLC N-(Azido-PEG4)-N-Boc-PEG4-NHS ester | 2112731-96-9 | ≥97.0% | 25 MG

N-(Azido-PEG4)-N-Boc-PEG4-NHS ester is a PEG-based PROTAC linker, primarily utilized in the synthesis of PROTACs. It functions as a versatile click chemistry reagent due to its terminal azide group. This enables it to participate in copper-catalyzed azide-alkyne cycloaddition (CuAAc) with alkyne-containing molecules, as well as strain-promoted alkyne-azide cycloaddition (SPAAC) reactions with DBCO or BCN group-containing molecules.

Medchemexpress LLC Boc-NH-C4-Br | 164365-88-2 | 252.15 | 500 MG

Boc-NH-C4-Br is an alkyl chain-based PROTAC linker used in the synthesis of PROTACs. PROTACs are compounds that 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. They exploit the intracellular ubiquitin-proteasome system to selectively degrade target proteins.
