Product Information

Description	t-Boc-N-amido-PEG1-bromide is a PEG linker containing a bromide group and a Boc-protected amino group. The hydrophilic PEG spacer increases solubility in aqueous media. The bromide (Br) is a very good leaving group for nucleophilic substitution reactions. The Boc group can be deprotected under mild acidic conditions to form the free amine.
Synonyms	Br-PEG1-NHBoc; tert-Butyl (2-(2-bromoethoxy)ethyl)carbamate; Boc-NH-PEG1-Br; N-Boc-2-(2-bromoethoxy)ethanamine; BocNH-PEG1-CH2CH2Br; Carbamic acid, N-[2-(2-bromoethoxy)ethyl]-, 1,1-dimethylethyl ester; N-Boc-PEG1-bromide; 2-Methyl-2-propanyl [2-(2-bromoethoxy)ethyl]carbamate
