11-Bromo-1-undecanethiol
11-Bromo-1-undecanethiol (CAS: 116129-34-1), a versatile organobromine and thiol compound with the formula Br(CH2)10CH2SH, is an essential building block in organic synthesis. Its bifunctional nature, featuring both a terminal thiol and a terminal bromide, allows for selective reactions. This chemical is primarily utilised in materials science, surface modification, and the synthesis of complex organic molecules. It is supplied by Tech Serve Solutions with a purity of 99%.
Surface Modification
The thiol group readily chemisorbs onto noble metal surfaces (e.g., gold), forming self-assembled monolayers (SAMs). The terminal bromide can then be used for further functionalization or polymerisation, enabling tailored surface properties for applications in sensors and electronics.
Organic Synthesis
As a bifunctional building block, it is valuable in constructing complex organic architectures. The thiol can participate in nucleophilic substitution or addition reactions, while the bromide can undergo coupling reactions or nucleophilic displacement.
Materials Science
It serves as a monomer or cross-linking agent in the development of novel polymers and functional materials. The incorporation of the long alkyl chain and the reactive end groups can impart specific physical and chemical characteristics to the final material.
