Used primarily in organic synthesis as a protecting group for hydroxylamine. It helps in the selective modification of molecules by temporarily masking the hydroxylamine functionality during complex reactions. This is particularly useful in the synthesis of peptides and other sensitive compounds where hydroxylamine might interfere with the desired chemical transformations. Additionally, it finds application in the preparation of active pharmaceutical ingredients (APIs) where controlled reactivity is crucial. Its stability under various reaction conditions makes it a valuable reagent in multi-step synthetic processes.
