SUNBRIGHT GL2-200NP

2arm branched PEG, -COO-pNP, Mw 20,000
Chemical Name: 2,3-Bis(methylpolyoxyethylene-oxy)-1-(4-nitrophenoxy carboxy) propane
CAS#: 697278-22-1

SUNBRIGHT GL2-200NP is a 2-arm branched p-nitrophenyl carbonate-PEG with a total molecular weight of 20 kDa (10 kDa per PEG arm). The p-nitrophenyl carbonate group reacts with amine-containing molecules to form a stable carbamate bond. We originally developed and introduced this type of 2-arm branched activated PEG, which has already been successfully utilized in several marketed PEGylated drugs, demonstrating its practical utility and reliability in therapeutic applications.
