BrCH2CONH-PEG8-COOtBu

 CAS No.: 2055041-16-0  Cat No.: BP-501366  Purity: ≥95% 4.5  

BrCH2CONH-PEG8-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.
