Used as a reagent in organic synthesis, particularly in the preparation of oximes and nitrones. It serves as a hydroxylamine equivalent in the conversion of carbonyl compounds to their corresponding O-substituted derivatives, enabling selective protection or functionalization in multi-step syntheses. Its stability and reactivity make it valuable in pharmaceutical research, especially in the development of bioactive molecules and heterocyclic compounds. Commonly employed in the synthesis of intermediates for agrochemicals and medicinal agents where controlled oxime formation is required.
