  • Applications

    p-Butoxytoluene (CAS 10519-06-9) is primarily used as an industrial intermediate and solvent in organic synthesis. In fragrance and cosmetics, it may function as a fragrance intermediate or solvent in formulations. In household products, it can act as a solvent and processing aid in cleaners and detergents. In coatings and inks, it is employed as a co-solvent or processing solvent to adjust volatility and flow. In polymers and plastics, it serves as an intermediate for resin components or as a processing aid in polymer formulations. In industrial manufacturing, it is used as a chemical intermediate for the synthesis of other aromatic compounds. Its use is subject to local regulations and formulation limits.
