SUNBRIGHT ME-300CS
Methoxy-PEG-CO(CH2)2COO-NHS, Mw 30,000
Chemical Name: α-Succinimidyloxysuccinyl-ω-methoxy, polyoxyethylene
CAS#: 78274-32-5
SUNBRIGHT ME-300CS is a methoxy PEG NHS ester with a 30,000 Da PEG chain. The NHS group is linked to the PEG chain via a succinic acid linker, and it readily reacts with amine-containing molecules to form a stable amide bond. After PEGylation, the CS type is relatively susceptible to hydrolysis because it contains an ester linkage, enabling the control of hydrolysis rate depending on the target applications.
