Properties

Description

This product is a monodisperse methoxy-terminated polyethylene glycol (m-PEG) derivative equipped with a single reactive thiol group. The unreactive methyl ether cap prevents unwanted crosslinking, ensuring monofunctional reactivity exclusively through the thiol group. Its precise seven-unit ethylene glycol backbone ensures high reproducibility in bioconjugation chemistry.
