Propargyl-PEG4-alcohol - 98%, high purity , CAS No.208827-90-1
Basic Description Synonyms 208827-90-1|2-(2-(2-(PROP-2-YNYLOXY)ETHOXY)ETHOXY)ETHANOL|Propargyl-PEG3-OH|Triethylene Glycol Mono(2-propynyl) Ether|2-[2-(2-prop-2-ynoxyethoxy)ethoxy]ethanol|2-{2-[2-(Prop-2-yn-1-yloxy)ethoxy]ethoxy}ethanol|MFCD13189984|2-{2-[2-(prop-2-yn-1-yloxy)ethoxy Specifications & Purity 98% Storage Temp Store at -20°C Shipped In Dry ice Product Description Propargyl-PEG4-alcohol is a PEG derivative containing a hydroxyl group and a propargyl group. The hydroxyl group enables further derivatization or replacement with other reactive functional groups. The propargyl group can be reacted with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield a stable triazole linkage. The hydrophilic PEG spacer increases solubility in aqueous media.
