Used in skincare formulations for its ability to absorb UV light, particularly in the UVA range, helping to protect the skin from sun damage. It functions as a photostabilizer in sunscreens, enhancing the effectiveness and longevity of other UV filters. Also employed in the synthesis of other organic compounds, including dyes and pharmaceuticals, due to its conjugated structure and functional groups. Its derivative forms are explored in research for potential use in photodynamic therapy and as fluorescent probes in biochemical studies.
