  • Applications

    Buntansin A (CAS 52525-63-0) is primarily encountered as an intermediate in organic synthesis and can function as a solvent or processing aid in industrial manufacturing. In formulations, it may be explored as a functional additive for coatings and inks, and it could be evaluated for use in polymer systems as a plasticizer or compatibility agent. The compound is sometimes considered for cosmetics/personal care formulations where permitted, and it may be evaluated as a synthetic intermediate in pharmaceutical or agrochemical research. Overall, its applications are formulation- and regulation-dependent, and uses would be defined by local requirements and product specifications.
