BrCH2CONH-PEG3-COOtBu

 CAS No.: 1807537-33-2  Cat No.: BP-500665  Purity: ≥95% 4.5  

BrCH2CONH-PEG3-COOtBu is a PEG linker containing a bromide group and a t-butyl-protected carboxyl group. The hydrophilic PEG spacer increases solubility in aqueous media. The bromide (Br) is a very good leaving group for nucleophilic substitution reactions. The t-butyl-protected carboxyl group can be deprotected under acidic conditions.
