  • Applications

    Sennidin B (CAS 517-44-2) is a hydroxyanthracene-type derivative found in the senna plant; in practice it is used as an intermediate in the synthesis of anthraquinone derivatives and as a reference material for analytical characterization. Potential applications include serving as a precursor for dyes and pigments used in polymers, plastics, and coatings; acting as a research reagent in organic synthesis and natural product chemistry; and being evaluated as a starting point for derivative development in pharmaceutical research. Use is subject to local regulations and formulation limits.
