N-(Boc-PEG3)-N-bis(PEG2-alcohol) - 97%, high purity , CAS No.2055042-60-7
Basic Description Synonyms tert-butyl (1-hydroxy-9-(2-(2-(2-hydroxyethoxy)ethoxy)ethyl)-3,6,12,15,18-pentaoxa-9-azaicosan-20-yl)carbamate | tert-butyl N-(20-hydroxy-12-{2-[2-(2-hydroxyethoxy)ethoxy]ethyl}-3,6,9,15,18-pentaoxa-12-azaicosan-1-yl)carbamate | C70721 | AKOS040742229 | C Specifications & Purity ≥97% Storage Temp Store at -20°C Shipped In Ice chest + Ice pads Product Description N-(Boc-PEG3)-N-bis(PEG2-alcohol) is a branched PEG linker with a Boc protecting group and two PEG2-alcohol branches connected to a central nitrogen. The Boc can be removed under acidic conditions. The hydroxyl groups can be reacted the further derivatize the compound. The hydrophilic PEG linkers increase the water solubility of the compound. Branched PEG linkers have increased conjugation efficiency.
