  • Applications

    8-(sec-Butyl)quinoline (CAS 67634-06-4) may be used primarily as an intermediate in the synthesis of quinoline-based compounds for pharmaceutical and dye applications, and is often considered a fragrance ingredient/odorant for perfumery and cosmetics; in coatings, paints and ink formulations it can serve as an intermediate or specialty additive; it may also be evaluated for polymer or plastic formulations as a precursor or functional component, depending on formulation requirements and local regulations.
