FMOC-NH-PEG-SH (MW 5000)

FMOC-NH-PEG-SH (MW 5000) (FMOC-NH-PEG-Thiol (MW 5000) ) is a PEG derivative containing an Fmoc protecting group and a reactive thiol (-SH) functional group. The thiol group is highly active and can specifically react with various molecules to form stable covalent bonds. Fmoc serves as a common amino-protecting group, shielding the amine from unintended reactions until it is intentionally removed for specific coupling reactions.
