  • Applications

    Sodium 1-(2-carboxyethyl)-2-(heptadecenyl)-4,5-dihydro-1-(2-hydroxyethyl)-1H-imidazolium hydroxide, CAS 71929-17-4, is a task-specific ionic liquid (TSIL) with amphiphilic character, frequently used as a non-volatile solvent and reaction medium in organic synthesis and catalytic processes; the hydroxide counterion can provide basic conditions, enabling its use as a base in various transformations or as a base source in solvent systems; it also serves as a processing aid in polymerization media and as a dispersing or stabilizing solvent in coatings, inks, and polymer formulations; it is evaluated as a medium for separations and extractions, leveraging its tunable polarity and ionic nature; and it may be studied as an electrolyte or supporting medium in electrochemical systems such as batteries or capacitors, where ionic liquids offer thermal stability and ionic conductivity; overall, its applications span industrial manufacturing, coatings/inks, polymer science, separations, and electrochemistry.
