Product Information

Description	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.
Synonyms	Bromoacetamido-PEG3-t-butyl ester; Bromoacetamido-PEG3-C2-Boc; tert-butyl 1-bromo-2-oxo-6,9,12-trioxa-3-azapentadecan-15-oate; 4,7,10-Trioxa-13-azapentadecanoic acid, 15-bromo-14-oxo-, 1,1-dimethylethyl ester; 2-Methyl-2-propanyl 1-bromo-2-oxo-6,9,12-trioxa-3-azapentadecan-15-oate; 6,9,12-Trioxa-3-azapentadecan-15-oic acid, 1-bromo-2-oxo-, 1,1-dimethylethyl ester
