Fmoc-NH-PEG4-HZ-BOC - CAS 1263044-77-4

Fmoc-NH-PEG4-HZ-BOC is a PEG reagent with an Fmoc-protected amine and a Boc-protected acylhydrazide. The Fmoc group can be deprotected under basic conditions to yield a free amine available for further conjugation. The hydrophilic PEG spacer enhances solubility in aqueous media. Boc can be removed under mild acidic conditions to form an active acylhydrazide, which can then couple with various carbonyls.
