Propargyl-PEG6-acid

t-Boc-aminooxy-PEG5-propargyl is a click crosslinker. Propargyl group is reactive with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield a stable triazole linkage. T-Boc-aminooxy can be converted to free aminooxy under mild acidic conditions and then can react with an aldehyde or ketone. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
