N-(Aminooxy-PEG3)-N-bis(PEG4-t-butyl ester) is a branched aminooxy linker. It can react with aldehyde to form an oxime bond. If a reductant is used, it will form a hydroxylamine linkage. The t-butyl ester group can be hydrolyzed under acidic conditions. The hydrophilic PEG linkers increase the water solubility of the compound. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries. Aminooxy compounds are very reactive and sensitive; they cannot be stored for long term. Immediate use (within 1 week) is highly recommended.
