  • Applications

    Ethyl isopropyl ether (CAS 625-54-7) is primarily used as a solvent in industrial applications. It serves as a processing solvent in coatings, inks, and adhesives, aiding dissolution of resins and film formation. It is employed as a cleaning and degreasing solvent for metal parts and manufacturing equipment. In chemical manufacturing, it functions as a solvent medium or an intermediate solvent for organic synthesis and purification steps. It can also be used as a specialty extraction and purification solvent in laboratory workflows where volatility and selectivity are advantageous.
