t-Boc-N-Amido-PEG28-acid contains a terminal carboxylic acid and Boc-protected amino group. The PEG spacer increases the aqueous solubility of the resulting compound. The terminal carboxylic acid readily reacts with primary and secondary amine under EDC, DCC, HATU or other amide coupling conditions to form a stable amide bond. The Boc group can be deprotected under mild acidic conditions to form the free amine, which can undergo amide coupling with carboxylic acid bearing biomolecules.
T-Boc-N-amido-PEG28-acid is a biocompatible, water-soluble polymer used in biotechnological applications. It is a type of polyethylene glycol (PEG) linked to an N-amido group, which is then protected with a tert-butyloxycarbonyl group (t-Boc). This form of PEG is used to modify proteins and other molecules for research purposes.
