  • Applications

    2-Heptadecyl-4,5-dihydro-1,3-bis(2-hydroxyethyl)-1-H-imidazolium chloride (CAS 93783-42-7) is a designer ionic liquid commonly considered for real-world industrial applications. It is evaluated and used as a solvent or reaction medium for organic synthesis and polymer processing, aiding dissolution and transport of monomers and polymers in manufacturing. With a long alkyl chain and hydroxyethyl groups, it can act as an amphiphilic surfactant-like additive, and is thus explored as a formulation additive for coatings, lacquers, and inks to improve flow and phase stability. Due to the ionic liquid nature of the imidazolium, it is studied as an electrolyte component for electrochemical devices and electronics applications. Other potential uses include as a component in coatings/inks formulations and as a surfactant or dispersant in cleaning formulations, subject to local regulations and formulation limits.
