  • Applications

    1-Isobutoxypropan-2-ol (CAS 23436-19-3) is a secondary-alcohol-containing ether commonly used as a solvent and processing aid in multiple industries; in industrial coatings, inks, and adhesives it serves as a versatile vehicle for formulations, while it can function as a reactive-diluent to reduce viscosity in polymer and resin systems, including UV-curable systems; it also serves as an intermediate in chemical synthesis and may appear in cleaning formulations for industrial or household use; in fragrance applications it may act as a solvent or carrier for aroma compounds, subject to formulation constraints.
