4-Arm-PEG-N3

4-Arm azido-functionalized discrete poly(ethylene glycol) (4-Arm-PEG-N3) is a 4-arm precision PEG derivative. The PEG arms present terminal azide groups. Discrete chain lengths with different degrees of polymerization are available. The azide can undergo copper-catalyzed click reactions with terminal alkynes or copper-free click conjugation with strained alkynes such as DBCO and BCN. The multiarm structure provides attachment sites for multivalent ligand display or network construction. Arm number, chain length, and functional-group equivalents can be varied to compare crosslink spacing and molecular presentation. In this series, n denotes the number of ethylene glycol repeat units in each PEG arm.

Applications:

Four-arm PEG multivalent conjugation;
Branched PEG construction;
Crosslinking and site-density studies;
Azide click chemistry;
Bioorthogonal conjugation.

Customization available.
