Basic Description Synonyms EN300-7463690 | 3-(2-prop-2-ynoxyethoxy)propanoic acid | AKOS040742464 | Z2235772112 | C70437 | CS-0068466 | HY-118764 | MFCD29764323 | Propyne-PEG1-CH2CH2COOH | SY273042 | 3-(2-(Prop-2-yn-1-yloxy)ethoxy)propanoic acid | 3-[2-(prop-2-yn-1-yloxy)ethoxy]pro Specifications & Purity 98% Storage Temp Store at -20°C Shipped In Ice chest + Ice pads Product Description Propargyl-PEG2-acid is a PEG derivative containing a propargyl group with a terminal carboxylic acid. The terminal carboxylic acid can be reacted with primary amine groups in the presence of activators (e.g. EDC, or DCC) to form a stable amide bond. The hydrophilic PEG spacer increases solubility in aqueous media. 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.
