Fmoc-N-amido-dPEG®-t-boc-hydrazide, product number QBD-10043, is a heterobifunctional PEG modifier containing a short discrete PEG chain. It is useful in syntheses where an acid-labile hydrazone functionality is required.


Unit Size 100 mg, 1000 mg
Molecular Weight 601.69; single compound
Chemical formula C₃₁H₄₃N₃O₉
Purity > 98%
dPEG® Spacer is 18 atoms and 21.1 Å
Typical solubility properties (for additional information contact Customer Support) Methylene chloride, Acetontrile, DMAC or DMSO.
Storage and handling -20°C; Always let come to room temperature before opening; be careful to limit exposure to moisture and restore under an inert atmosphere; stock solutions can be prepared with dry solvent and kept for several days (freeze when not in use). dPEG® pegylation compounds are generally hygroscopic and should be treated as such. This will be less noticeable with liquids, but the solids will become tacky and difficult to manipulate, if care is not taken to minimize air exposure.
