2-Arm-PEG-Alkyne

2-Arm terminal alkyne-functionalized discrete poly(ethylene glycol) (2-Arm-PEG-Alkyne) is a 2-arm precision PEG derivative. The PEG arms present terminal terminal alkyne groups. Discrete chain lengths with different degrees of polymerization are available. The terminal alkyne can undergo suitable copper-catalyzed cycloaddition with azides, linking the PEG spacer to target molecular modules. 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:

Two-arm PEG multivalent conjugation;
Branched PEG construction;
Crosslinking and site-density studies;
Copper-catalyzed azide–alkyne click chemistry;
Probe and ligand assembly.

Customization available.
