1,3-Bis-aminooxy propane is a samll molecule PEG reagent containing two aminooxy groups. It can react with an aldehyde to form an oxime bond. If a reductant is used, it will form a hydroxylamine linkage. Aminooxy compounds are very reactive and sensitive; they cannot be stored for long term. Immediate use (within 1 week) is highly recommended.

1,3-Bis-aminooxy propane is an alkyl chain-based PROTAC linker that can be used in the synthesis of PROTACs[1].
