BCN-PEG2-PFP ester (CAS 1421932-53-7) is a bifunctional PEG (polyethylene glycol) reagent, having BCN (bicyclononyne) and PFP ester groups. BCN, used in copper-free click chemistry, forms stable triazole linkages with azides. PEG2 is a biocompatible polymer with two repeating units. PFP ester is a reactive ester, which reacts with amines to form stable amide bonds. This compound can be used in biochemical research areas such as drug delivery and surface modification.
AxisPharm offers 5000+ PEG Linkers with high purity. Different kinds of PEG Reagents may be available by custom synthesis.
