| Hazard Information | Back Directory | [Description]
Propargyl-PEG2-acid is a linker consisting of propargyl and carboxylic acid functional groups. In the presence of activators (e.g. EDC, or HATU), the carboxylic acid reacts with primary amine to form a stable amide bond. The propargyl group reacts with azide group in biomolecules to yield a stable triazole linkage. | [Uses]
Propargyl-PEG2-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-PEG2-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. | [reaction suitability]
