  • Applications

    Tambulin (CAS 571-72-2) is an organic compound that may serve as an intermediate in organic synthesis and, in some formulations, as a solvent or processing aid in manufacturing. It is commonly evaluated for potential applications across fragrance, cosmetics and personal care, household products, coatings and inks, polymers and plastics, and broader industrial manufacturing, where it may function as a component in fragrance formulations, a solvent or processing aid, or a niche additive, all subject to local regulations and formulation limits.
