Used as a hypervalent iodine reagent in organic synthesis, particularly for oxidative transformations. It serves as a powerful and selective oxidant in the conversion of alcohols to carbonyl compounds, and in the functionalization of C–H bonds. Commonly employed in heterocycle synthesis and in the preparation of complex molecules in pharmaceutical and natural product synthesis. Its stability and low toxicity make it a preferred choice over heavy metal oxidants. Also utilized in radical reactions and cyclization processes where mild oxidative conditions are required.
