Used as a versatile reagent and catalyst in organic synthesis, particularly in oxidation reactions. It facilitates selective oxidation of sulfides to sulfoxides and can act as an oxygen transfer agent in various transformations. Commonly employed in pharmaceutical synthesis due to its stability and reactivity under mild conditions. Also serves as a ligand or intermediate in metal-catalyzed reactions, enhancing selectivity and yield. Its polarity and basicity make it useful in chromatographic separations and as a buffering agent in certain analytical procedures.
