FMOC-NH-PEG-SH (MW 2000)

FMOC-NH-PEG-SH (MW 2000) (FMOC-NH-PEG-Thiol (MW 2000) ) is a PEG derivative with an Fmoc protecting group and a thiol (-SH) reactive group. The thiol group is a highly reactive chemical group that can react specifically with a variety of molecules to form stable covalent bonds. Fmoc is a commonly used amino protecting group that protects the amino group from unwanted reactions until it is removed when a specific coupling reaction is required.
