Bis-Mal-Lysine-PEG4-TFP ester - 98%, high purity , CAS No.1426164-53-5
Basic Description Synonyms Bis-Mal-Lysine-PEG4-TFPester | Bis-Mal-Lysine-PEG4-TFP ester | SCHEMBL23659153 | 4,7,10,13-Tetraoxa-16,23-diazahexacosanoic acid, 26-(2,5-dihydro-2,5-dioxo-1H-pyrrol-1-yl)-18-[[3-(2,5-dihydro-2,5-dioxo-1H-pyrrol-1-yl)-1-oxopropyl]amino]-17,24-dioxo-, 2,3, Specifications & Purity ≥98% Storage Temp Store at -20°C Shipped In Ice chest + Ice pads Product Description Bis-Mal-Lysine-PEG4-TFP ester contains two malimide end groups which can react with thiol groups from pH 6.5 to 7.5 to form thiolester bonds. The TFP ester can be reacted with primary amine groups and is also less susceptible to undergo hydrolysis compared to NHS ester. The hydrophilic PEG linker increases the compound's water solubility in aqueous environments.
