H2N-PEG-N3

Azido-PEG4-Amine (H2N-PEG-N3) is a heterobifunctional precision PEG derivative with a defined chain length. The two ends bear azide and primary amine groups, respectively. Discrete chain lengths with different degrees of polymerization are available. The azide supports conjugation through azide–alkyne click chemistry. The terminal amine can be further modified through amidation or other functional-group transformations, enabling bioconjugation, drug modification, and synthesis of functional PEG derivatives and precision molecular linkers.
