Description

1,18-Dibromooctadecane is a high-purity, long-chain aliphatic dibromide compound, serving as a critical bifunctional alkylating agent and building block in advanced organic synthesis. Its value lies in its ability to introduce a linear C18 spacer with reactive bromine termini, enabling the construction of polymers, macrocycles, and complex molecular architectures. This product is essential for researchers and manufacturers in the pharmaceutical, polymer science, and specialty chemical industries seeking reliable, high-quality intermediates for their development and production processes.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) and prodrugs, particularly those requiring lipophilic chain incorporation.
• Polymer Chemistry: Acts as a monomer or chain extender in the production of polyethers, polyesters, and other specialty polymers, influencing material properties like flexibility and crystallinity.
• Surfactant & Phase-Transfer Catalyst Synthesis: Serves as a key precursor for manufacturing quaternary ammonium compounds and cationic surfactants.
• Material Science: Employed in the creation of liquid crystals, dendrimers, and other advanced organic materials with specific self-assembly properties.
• Cross-linking Agent: Utilized to cross-link polymers, enhancing thermal stability and mechanical strength in final products.
• Organic Synthesis Building Block: A versatile reagent for nucleophilic substitution reactions (SN2), facilitating the introduction of long alkyl chains into target molecules.
