Propargyl-PEG5-acid - 98%, high purity , CAS No.1245823-51-1
Basic Description Synonyms Alkyne-PEG5-COOH | EN300-7373222 | 3-[2-[2-[2-(2-prop-2-ynoxyethoxy)ethoxy]ethoxy]ethoxy]propanoic acid | AMY4517 | MS-24393 | Propargyl-PEG4-CH2CH2COOH | SB67191 | LCZC1118 | SCHEMBL932686 | 1245823-51-1 | 4,7,10,13,16-Pentaoxanonadec-18-yn-1-oic acid | Specifications & Purity 98% Storage Temp Store at -20°C Shipped In Ice chest + Ice pads Product Description Propargyl-PEG5-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.
