Used as a highly effective organic photocatalyst in visible-light-mediated reactions. It enables a variety of photoredox transformations, including C–H functionalization, cross-coupling, and radical addition reactions under mild conditions. Particularly valued in synthetic chemistry for promoting reactions with high selectivity and efficiency using low catalyst loadings. Its strong oxidizing power in the excited state makes it suitable for challenging single-electron transfer processes. Commonly applied in pharmaceutical and agrochemical research for constructing complex molecular architectures.
