Used primarily in research settings to study the carcinogenic effects of tobacco-specific nitrosamines. It serves as a model compound to investigate the mechanisms of DNA damage and tumor formation caused by nitrosamines. Additionally, it is employed in toxicology studies to assess the health risks associated with tobacco use and to develop strategies for reducing exposure to harmful tobacco byproducts. Its role in understanding the biochemical pathways of nitrosamine-induced cancers has contributed to advancements in cancer prevention and public health policies.
