Used as a photoredox catalyst in organic synthesis, enabling light-driven reactions such as C–H functionalization and cross-coupling under mild conditions. Its strong oxidizing ability in the excited state allows for efficient electron transfer processes. Commonly applied in late-stage functionalization of complex molecules due to high selectivity and stability. Also employed in mechanistic studies involving radical intermediates because of its predictable redox behavior. Suitable for reactions under visible light irradiation, making it valuable in sustainable chemistry approaches.
