Used as a stable, highly efficient oxidizing agent in organic synthesis, particularly for the selective oxidation of alcohols to carbonyl compounds under mild conditions. It is especially effective in the presence of acid-sensitive functional groups due to its near-neutral pH profile. Commonly employed in peptide chemistry for oxidizing N-terminal serine or threonine residues during synthesis. Also utilized in electrochemical applications as a mediator in redox reactions. Its stability and solubility in polar solvents make it suitable for both solution-phase and solid-phase reactions.
