Used as a photoredox catalyst in organic synthesis, enabling light-driven reactions such as C–C and C–N bond formations under mild conditions. Commonly applied in cross-coupling reactions, radical additions, and cyclizations where traditional metal catalysts may fail. Its strong oxidizing power in the excited state allows activation of substrates through single-electron transfer processes. Also employed in materials science for developing photoresponsive systems and in medicinal chemistry for synthesizing complex bioactive molecules. Stable under ambient conditions and compatible with a wide range of functional groups, making it suitable for diverse reaction setups.
