Product Information

Description	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.
Synonyms	Bromoacetamido-PEG8-C2-Boc; Bromoacetamido-PEG8-t-butyl ester; tert-butyl 1-bromo-2-oxo-6,9,12,15,18,21,24,27-octaoxa-3-azatriacontan-30-oate; 4,7,10,13,16,19,22,25-Octaoxa-28-azatriacontanoic acid, 30-bromo-29-oxo-, 1,1-dimethylethyl ester; 2-Methyl-2-propanyl 1-bromo-2-oxo-6,9,12,15,18,21,24,27-octaoxa-3-azatriacontan-30-oate; 6,9,12,15,18,21,24,27-Octaoxa-3-azatriacontan-30-oic acid, 1-bromo-2-oxo-, 1,1-dimethylethyl ester
