Used primarily as an intermediate in the synthesis of pharmaceuticals and agrochemicals. It serves as a building block in the preparation of certain nitrogen-containing heterocyclic compounds. Due to the presence of the nitroso group, it can participate in nitrosation reactions and is sometimes employed in research related to nitrosamine formation, which is relevant in toxicology and carcinogenicity studies. Its derivatives may be explored in medicinal chemistry for potential biological activity, though the compound itself is not used directly in final products due to stability and safety concerns.
