Application

Propargyl-PEG1-acid is a heterobifunctional, PEGylated crosslinker featuring a carboxylic acid at one end and propargyl group at the other for reaction with azide-containing compounds using click chemistry. The hydrophillic PEG linker facilitates solubility in biological applications. Propargyl-PEG1-acid can be used for bioconjugation or as a building block for synthesis of small molecules, conjugates of small molecules and/or biomolecules, or other tool compounds for chemical biology and medicinal chemistry that require ligation. Examples of applications include its synthetic incorporation into antibody-drug conjugates or proteolysis-targeting chimeras (PROTAC® molecules) for targeted protein degradation.
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.
