Used primarily in research settings as a nitrosamine compound to study carcinogenesis and mutagenicity. It serves as a model substance for investigating the biological effects of exposure to nitrosamines, which are known to be potent carcinogens. Commonly employed in toxicology studies to assess DNA damage, metabolic activation pathways, and organ-specific tumor formation, particularly in the urinary bladder. Due to its instability and health hazards, it is not used in commercial or industrial applications but remains valuable in controlled laboratory experiments related to cancer research and chemical safety evaluation.
