  • Applications

    Dipropoxymethane (CAS 505-84-0) is mainly used as a solvent and a chemical intermediate in industrial formulations. It is commonly employed as a solvent in coatings, inks, and cleaning products, and may function as a reactive diluent in certain coating formulations. It also serves as a feedstock for the synthesis of acetals and related intermediates, and as a precursor in the manufacture of specialty polymers and resins in industrial manufacturing.
