  • Applications

    Ethyl butanol (CAS 97-95-0) is a versatile solvent and synthesis intermediate used across multiple industries. It is employed as a solvent in coatings, inks, and adhesive formulations; it also serves as a precursor for fragrance esters in perfumery and is used in cleaning and degreasing formulations for industrial applications. In polymer processing and plastics formulations, it acts as a solvent and processing aid. In cosmetics and personal care, it may be used as a solvent or processing aid where permitted by formulation guidelines.
