| Hazard Information | Back Directory | [Description]
Amino-PEG9-t-butyl ester is a PEG molecule with an amino group and a t-butyl protected carboxyl group (tBoc). 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. |
