What is Amino-PEG10-t-butyl ester?
Description
Amino-PEG10-t-butyl ester is a water soluble PEG reagent containing an amino group with a t-butyl protected carboxyl group. 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 t-butyl protected carboxyl group can be deprotected under acidic conditions.
