Description and Uses

4-Arm PEG-OH is a multi-arm polyethylene glycol with hydroxyl groups at each terminal of the four arms. Pentaerythritol core is used in 4arm PEG raw materials and derivatives. The indicated molecular weight of the multi-arm PEG is the sum of the molecular weights of all the arms.

4-arM Poly(ethylene glycol) is a multi-armed PEG reagent with 4 reactive groups for PEGylation, hydrogels, crosslinking, coating, nanoparticles, and polymer-drug conjugates. Applications include tissue engineering, drug delivery formulations, diagnostic assays, and pharmaceutical and cosmetic R&D.
