JenKem Technology now provides various kinds of multi-arm heterobifunctional PEG derivatives as regular products or through Custom Synthesis.
Multi-arm Heterobifunctional PEG Derivatives are advanced polymeric building blocks featuring multiple reactive ends with distinct chemical functionalities. Synthesized via controlled ring-opening polymerization, these branched architectures enhance drug solubility and circulation half-life. Specific molecular formulas and CAS numbers vary by arm count and end-group chemistry.
Store under inert atmosphere at 2-8°C to prevent hydrolysis. Strict moisture control is mandatory during handling. Clinical use requires rigorous purification to remove unreacted monomers and ensure biocompatibility.
