Product Information

Description	Br-PEG12-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	Bromo-PEG12-t-butyl ester; Br-PEG12-CH2CH2COOtBu; Bromo-PEG12-C2-Boc; 2-Methyl-2-propanyl 1-bromo-3,6,9,12,15,18,21,24,27,30,33,36-dodecaoxanonatriacontan-39-oate; 3,6,9,12,15,18,21,24,27,30,33,36-Dodecaoxanonatriacontan-39-oic acid, 1-bromo-, 1,1-dimethylethyl ester; tert-butyl 1-bromo-3,6,9,12,15,18,21,24,27,30,33,36-dodecaoxanonatriacontan-39-oate
