Used as a reagent in organic synthesis, particularly in the preparation of hydroxylamine derivatives for pharmaceutical and agrochemical applications. It serves as a protected form of hydroxylamine, allowing selective reactions in multi-step syntheses. Commonly employed in the formation of oximes and nitrones, which are key intermediates in the development of bioactive molecules. Its stability and solubility profile make it suitable for use in peptide coupling and modification of carbonyl compounds under mild conditions.
