Amino-EG6-undecanethiol, hydrochloride

20-(11-Mercaptoundecanyloxy)-3, 6, 9, 12, 15, 18-hexaoxaeicosane-1-amine, hydrochloride . Application: SAM preparation, amine group coating, and hydrophilic surface.

Polyethyleneglycols (PEGs) are widely used for material modifications to improve hydrophilicity of the surface. PEG-coated materials are usually more stable under physiological conditions. Since Amino-EG6-undecanethiol has 6 ethylene glycol units, 11 carbon atoms, and an SH group at the end, it can be used to prepare a highly oriented and hydrophilic SAM on a gold surface. This is suitable for biomaterial labeling on the surface due to the improved hydrophilicity.
