What is 5,8,11-Trioxa-2-azatridecanoic,13-amino,1,1-dimethylethyl ester?
Description
t-Boc-N-Amido-PEG3-amine is a PEG linker with an amino group and Boc-protected amino. The hydrophilic PEG spacer increases solubility in aqueous media. The amino group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. The Boc group can be deprotected under mild acidic conditions to free the amine.
Chemical properties
Colorless viscous liquid
