  • Applications

    Cyclobranol (CAS 25692-13-1) is used as an industrial processing aid and chemical intermediate; it is commonly employed as a solvent or diluent in coatings, inks, and adhesives formulations, and serves as a building block in organic syntheses for specialty chemicals. It may function as a plasticizer or stabilizer in certain polymer systems, and is sometimes evaluated for fragrance applications as a carrier or solvent in perfumery formulations. Additionally, it can be used as a cleaning solvent or component in industrial cleaning products, subject to local regulations and formulation limits.
