Description

11-Bromo-1-Undecanethiol is a bifunctional organic compound featuring both a reactive bromoalkyl terminus and a thiol group, making it a versatile building block for surface chemistry and material science. Its primary value lies in its ability to form self-assembled monolayers (SAMs) on gold and other metal surfaces, creating well-defined organic interfaces. This product is essential for researchers and manufacturers in the nanotechnology, biosensor, and advanced materials sectors who require precise surface functionalization.

Application

• Formation of self-assembled monolayers (SAMs) on gold, silver, and copper surfaces for corrosion inhibition or surface patterning.
• Key intermediate in the synthesis of functionalized nanoparticles and quantum dots for diagnostic and imaging applications.
• Surface linker for immobilizing biomolecules (e.g., proteins, DNA) on biosensor chips and microarrays.
• Modification of electrode surfaces to enhance selectivity and performance in electrochemical sensors.
• Precursor for creating hydrophobic or specific chemical functionality on material surfaces.
• Building block in polymer and dendrimer synthesis, utilizing both the thiol and bromo groups for sequential reactions.
• Research and development of novel organic-inorganic hybrid materials and nanocomposites.
