Used primarily in scientific research as a potent carcinogenic compound, this chemical serves as a model substance for studying tobacco-related cancers. It is frequently employed in toxicology and oncology studies to understand the mechanisms of nitrosamine-induced DNA damage and tumor formation. Due to its high reactivity and mutagenic properties, it helps evaluate the effectiveness of chemopreventive agents and the metabolic pathways involved in carcinogen activation. Its application is restricted to controlled laboratory environments given its hazardous nature.
