Basic Description Synonyms Propargyl-PEG2-acid | 1859379-85-3 | 3-(2-(Prop-2-yn-1-yloxy)ethoxy)propanoic acid | 3-(2-prop-2-ynoxyethoxy)propanoic acid | Propyne-PEG1-CH2CH2COOH | MFCD29764323 | 3-[2-(prop-2-yn-1-yloxy)ethoxy]propanoic acid | SCHEMBL12092183 | AKOS040742464 | BP-23165 | BS-52151 | SY2730 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.
