  • Applications

    Luteolinidol chloride (CAS 1154-78-5) is primarily viewed as a synthetic intermediate, particularly for preparing flavonoid-derived compounds and colorants, and can be used as a precursor for pigments in coatings and inks. In pharmaceutical chemistry and organic synthesis, it is often evaluated as a precursor or building block for flavonoid-related compounds for research and development. It may also be considered as a potential ligand or chelating agent in coordination chemistry and may serve as a functional component in polymer or nano-composite formulations to impart color or stability. Applications depend on local regulations and formulation limits.
