m-PEG7-thiol
m-PEG7-thiol is a high-purity monofunctional PEG derivative featuring a single thiol (-SH) group for site-specific conjugation. The PEG7 spacer enhances hydrophilicity, increases solubility, and reduces steric hindrance, specifically enabling efficient coupling in both aqueous and organic systems.
