Uses

Used in Polymer Synthesis:
Bis[2-(2-broMoisobutyryloxy)undecyl] disulfide 97% is used as an Atom Transfer Radical Polymerisation (ATRP) initiator for the functionalization of noble metal surfaces. Its unique structure allows for the controlled growth of polymer chains on these surfaces, which can be beneficial in various applications such as catalysis, sensors, and drug delivery systems.
Used in the Preparation of Polymer Brushes:
Bis[2-(2-broMoisobutyryloxy)undecyl] disulfide 97% is also utilized in the preparation of polymer brushes, which are thin layers of polymer chains attached to a solid surface. The broMoisobutyryloxy functional groups in Bis[2-(2-broMoisobutyryloxy)undecyl] disulfide 97% enable the formation of these brushes, which can be used in applications such as lubrication, adhesion, and surface modification.
Used in the Production of Biodegradable Hydrogels:
Bis[2-(2-broMoisobutyryloxy)undecyl] disulfide 97% is used as a key component in the synthesis of biodegradable hydrogels. These hydrogels have a wide range of applications, including drug delivery, tissue engineering, and wound healing, due to their biocompatibility, tunable mechanical properties, and ability to degrade over time.
Used in the Introduction of Temperature and Light Sensitive Cleavable Regions:
Bis[2-(2-broMoisobutyryloxy)undecyl] disulfide 97% can be used to introduce temperature and light-sensitive cleavable regions into polymers. This feature can be advantageous in applications where controlled degradation or release of a substance is desired, such as in drug delivery systems or smart materials that respond to environmental changes.

Directing self-assembly of nanoparticles at water/oil interfaces

Finding the right angle: The contact angle of nanoparticles at the water/oil interface can be engineered close to 90° by capping with ligands containing carboxylic ester terminal groups. This drives the nanoparticles to self-assemble into close-packed films (see picture), and thus provides the opportunity to create two- or three-dimensional homo- or heterogeneous nanostructures for electronic, optoelectrical, and magnetic applications.

Thermosensitive copolymer networks modify gold nanoparticles for nanocomposite entrapment

The core-shell gold nanoparticles and copolymer of N-isopropylacrylamide (NIPAM) and N,N′-methylenebisacrylamide (MBAA) hybrids (Au@copolymer) were fabricated through surface-initiated atom-transfer radical polymerization (ATRP) on the surface of gold nanoparticles in 2-propanol/water mixed solvents. The surface of citrate-stabilized gold nanoparticles was first modified by a disulfide initiator for ATRP. The slight crosslinking polymerization between NIPAM and MBAA occurred on the gold surface and resulted in the formation of core-shell Au@copolymer nano-structures that were characterized by TEM, and FTIR and UV-visible spectroscopy. Such synthesized Au@copolymer hybrids possess clearly thermosensitive properties and exhibit "inspire" and "expire" water behavior in response to temperature changes in aqueous solution. Because of this property, we enable to trap and encapsulate smaller nanoparticles by using the free space of the copolymer-network scaffold anchored at the gold surface.

Efficient two-step synthesis of 11,11′-dithiobis[1-(2-bromo-2- methylpropionyloxy)undecane], a conventional initiator for grafting polymer brushes from gold surfaces via ATRP

11,11′-Dithiobis[1-(2-bromo-2-methylpropionyloxy)undecane], a conventional initiator for grafting polymers from gold surfaces, was synthesized in two steps from 11-mercapto-1-undecanol in 88-92% overall yield. Oxidative dimerization of 11-mercapto-1-undecanol with a catalytic amount of sodium iodide and 30% hydrogen peroxide in ethyl acetate proceeded in 96% yield. Esterification with 2-bromoisobutyryl bromide in dichloromethane was clean and almost quantitative (92% yield) with pyridine used as base, whereas triethylamine gave a messy reaction (64% yield). Alternatively, esterification with 2-bromo-2-methyl-propanoic acid in dichloromethane occurred readily under Steglich′s conditions with N,N′-dicyclohexylcarbodiimide (DCC) and a catalytic amount of dimethylaminopyridine (DMAP; 88% yield).
