Tetra-n-hexylammonium iodide (CAS 2138-24-1) is a long-chain quaternary ammonium salt with four hexyl groups that give it a distinct lipophilic character. It’s well-suited for applications where purity and supply consistency are critical, including electrochemical research, materials science and phase-transfer. Iofina’s fully vertical production model delivers the purity and supply consistency these applications demand.
Tetra-n-hexylammonium iodide is a quaternary ammonium salt in which four n-hexyl chains are bonded to a central nitrogen atom, paired with an iodide counterion. It has a molecular formula of C24H52IN and a molecular weight of 481.59 g/mol.
Also known as tetrahexylammonium iodide, the compound is a white to off-white crystalline solid with a melting point of 99 to 101° Celsius. Although it is soluble in methanol and dichloromethane, it has limited water solubility. As a hygroscopic material, it should be stored in a cool, dark environment under an inert atmosphere to maintain product integrity and prevent moisture uptake.
Tetrahexylammonium iodide plays a critical role in research and industrial applications, where its long alkyl chains and iodide counterion work together to enable precise ionic and interfacial chemistry. Common applications include:
Phase-transfer catalysis: Facilitates the transfer of ions between immiscible aqueous and organic phases, improving the efficiency of organic synthesis reactions
Electrochemical research: Functions as a supporting electrolyte in non-aqueous electrochemical systems, where its lipophilic character enables stable ionic conductivity
Ionic liquid applications: Acts as a precursor or component in ionic liquid formulations used in materials science and specialty synthesis
Colloidal quantum dot synthesis: Serves as a capping agent to control surface chemistry, directly influencing optical and electronic performance
Iofina is one of North America’s leading iodine producers, providing advantages across the supply chain that few specialty chemical manufacturers can match. Through our proprietary WET® IOsorb® technology, we extract iodine from produced water brine streams and convert it into high-purity iodide salts in-house. Vertical integration provides full oversight across each production phase, with strict quality control at every step.
For researchers and procurement teams working in electrochemistry, materials science, phase-transfer catalysis and similar applications, these capabilities result in consistent material quality, reliable availability and technical support from a team that has been developing halogen-based specialty compounds since 1983.
Iofina has the production capabilities and technical expertise to meet your tetra-n-hexylammonium iodide supply needs with reliability and precision. Call 859-356-8000 to discuss your requirements or contact us online to request a quote.
