SUNBRIGHT MENP-40T

Methoxy-PEG-COO-pNP, Mw 40,000
Chemical Name: α-Methoxy-ω-(4-nitrophenoxy carbonyl), polyoxyethylene
CAS#: 124661-64-9

SUNBRIGHT MENP-40T is a methoxy PEG p-nitrophenyl carbonate with a 40,000 Da PEG chain. The p-nitrophenyl carbonate group reacts with amine-containing molecules to form a stable carbamate bond. After PEGylation, the formed carbamate bond is relatively resistant to hydrolysis, making it suitable for the applications that require prolonged stability under aqueous or physiological conditions.
