  • Applications

    Taxodione (CAS 19026-31-4) is primarily of interest in natural product chemistry and taxane-related research as an intermediate for the synthesis of taxane derivatives; it also serves as a reference material for isolation, structure elucidation, and analytical method development. In chemical synthesis, it can act as a redox-active building block for quinone-containing compounds, including pigment precursors for coatings and inks, and as a scaffold for organic electronic material research. In formulation and product development, it may be evaluated in cosmetics/personal care formulations or as a pigment precursor for cosmetics, depending on local regulations and formulation limits. It is also used as an analytical standard in method development for natural products.
