Product Information

Description	BrCH2CONH-PEG5-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.
Synonyms	Bromoacetamido-PEG5-C2-Boc; Bromoacetamido-PEG5-t-butyl ester; tert-butyl 1-bromo-2-oxo-6,9,12,15,18-pentaoxa-3-azahenicosan-21-oate
