Used primarily in research as an intermediate in organic synthesis, particularly in the development of pharmaceuticals and agrochemicals. It serves as a nitrosating agent in certain chemical reactions, enabling the introduction of nitroso groups into target molecules. Due to its reactivity, it is also studied in the context of nitrosamine formation, which has implications in toxicology and regulatory testing. Its derivatives are sometimes explored for potential biological activity, though the compound itself is not used directly in commercial products. Handling requires caution due to potential health risks associated with nitrosamines.
