DBCO-PEG4-TFP ester serves as a heterobifunctional PEG linker containing an azide-reactive DBCO click chemistry handle and an amine-reactive TFP ester that is less susceptible to undergo hydrolysis compared to NHS ester. The PEG spacer enhances the water-solubility of the compound. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
