Description:

WARNING: This product is for research use only, not for human or veterinary use.

Amino-PEG2-t-butyl ester is a PEG derivative containing an amino group with a t-butyl protected carboxyl group. 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. PEG Linkers may be useful in the development of antibody drug conjugates.
