Product Information

Description	BrCH2CONH-PEG6-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-PEG6-C2-Boc; Bromoacetamido-PEG6-t-butyl ester; tert-butyl 1-bromo-2-oxo-6,9,12,15,18,21-hexaoxa-3-azatetracosan-24-oate
