| Molecular weight | 239.85 |
|---|---|
| Linear formula | HSCH2(CH2)9CH2NH2 · HCl |
| Assay | 99% |
| Storage temperature | 2-8°C |
| Application | Creating SAMs containing amino functionalized sites.1 This molecule is used to modify gold surfaces with amine groups. The amine group is usually modified using amine-reactive materials, such as proteins or biomaterials, to further functionalize the gold surface. This material has also been self-assembled onto gold electrodes for a study on the effect of the terminal groups on the redox responses of ferrocene derivatives using the voltammetric method.2 Tanahashi and co-workers modified a gold surface with SAMs of several kinds of functionalized alkanethiols.3 |
| Melting point | 120-170 °C |
