Used primarily in research settings to study the formation and effects of N-nitroso compounds, which are known for their carcinogenic properties. It serves as a model compound to understand the mechanisms of nitrosation reactions and their implications in cancer development. Additionally, it is utilized in biochemical studies to investigate the role of proline derivatives in cellular processes and their potential interactions with nitrosating agents. This chemical aids in exploring the metabolic pathways and detoxification mechanisms related to nitroso compounds in biological systems.
