Hodoodo CAT#: H572131

CAS#: 165963-71-3

Description: N-Boc-PEG2-bromide is a PEG derivative containing a bromide group and Boc-protected amino group. The hydrophilic PEG spacer increases solubility in aqueous media. The bromide (Br) is a very good leaving group for nucleophilic substitution reactions. The Boc group can be deprotected under mild acidic conditions to form the free amine.
