Propargyl-PEG24-amine

Propargyl-PEG4-(CH2)3-CO2H is a linker containing a propargyl group at one end and a carboxylic acid at the other end. The carboxylic acid reacts with amine groups in the presence of activators (EDC or HATU). Under the catalyzation of copper, the propargyl group forms linkage with azide group of biomolecules. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Propargyl-PEG14-t-butyl ester consists of a propargyl group and a t-butyl protected carboxyl group. The propargyl group can be used in copper catalyzed Click Chemistry to yield a stable triazole linkage with azides. The t-butyl group can be hydrolyzed in acidic conditions. The hydrophilic PEG units help the molecule to have better solubility in aqueous environment. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
