  • Applications

    7,8-Dimethoxyflavone (CAS 65548-54-1) is primarily used as a synthetic intermediate and building block in chemical and pharmaceutical research, enabling the preparation of flavone frameworks and related compounds for medicinal chemistry development. It also serves as a reference material in analytical methods for flavonoids (e.g., HPLC/LC-MS) in laboratory settings. In cosmetics and personal care, it may be evaluated for applications as an antioxidant or a functional color-bearing component, subject to formulation constraints and local regulations. In industrial and materials contexts, it can act as a precursor for specialty polymers or coatings, where flavone cores are explored for incorporation into functional aryl systems.
