[Description]

Propargyl-PEG1-acid is a crosslinker with a propargyl group and a carboxylic acid group. The carboxylic acid reacts with primary amine under the activation of HATU or EDC. The propargyl group can participate in copper catalyzed azide-alkyne Click Chemistry reactions.
[Uses]

This is a crosslinker with an alkyne group on one end and a carboxyl group on the other end. The alkyne can be used to attach to an azide using copper-catalyzed click chemistry. The compound contains a single PEG unit to help improve solubility.
