Used as a key reagent in organic synthesis, particularly in the preparation of nitrogen-containing compounds such as amines and heterocycles. It serves as a protecting group for carbonyl compounds due to its ability to form stable oxime derivatives. Also employed in the synthesis of pharmaceutical intermediates, where its benzyl group can be easily removed under mild conditions. Plays a role in the development of agrochemicals and bioactive molecules, offering selective reactivity in multi-step reactions. Its hydroxylamine functionality makes it useful in radical reactions and as a nucleophile in substitution processes.
