3,4-Dibromo-Mal-PEG2-NHBoc

 CAS No.: 1807537-43-4  Cat No.: BP-501612  Purity: ≥95% 4.5  

3,4-Dibromo-Mal-PEG2-NHBoc is a hydrophilic PEG species containing a dibromomaleimide group and a Boc-protected amine. The dibromomaleimide group allows for two points of attachement because both of the bromine atoms can be substituted. The Boc protecting group can be removed under acidic conditions and allows for the amine to further react with other species. The hydrophilic PEG linker increases the compound's water solubility properties in aqueous media.
