  • Applications

    2'-Hydroxychalcone (CAS 1214-47-7) is commonly used as an organic synthesis intermediate and building block for flavonoid-like bioactive compounds, including scaffolds relevant to pharmaceutical and agrochemical research; it also serves as a chromophore precursor in the synthesis of dyes and pigments; in polymers and coatings it functions as a versatile unit for developing photoactive or UV-curable materials; and it is often evaluated for cosmetic formulation development as a precursor to functional additives with antioxidant or UV-protective potential.
