t-Boc Amine PEG Carboxyl is a protected polyethylene glycol linker featuring a tert-butyloxycarbonyl group on the amine terminus and a free carboxyl group. This bifunctional reagent facilitates site-specific conjugation in peptide synthesis via NHS ester coupling. The standard molecular formula is CnH2n+4On+1(C5H9O2)N, with CAS numbers varying by PEG chain length (e.g., 85067-59-2 for PEG4).
Store at -20°C under inert atmosphere to prevent hydrolysis of the Boc or carboxyl groups. Handle in a fume hood due to potential irritant properties; avoid contact with skin and eyes during manufacturing processes.
