NCIt definition : A clear, yellow, oily, liquid that is light sensitive and emits toxic fumes of nitrogen
oxides when heated to decomposition. N-Nitrosopiperidine is used in laboratory research
to induce tumors in experimental animals. This substance is naturally formed in foods
that contain sodium nitrite as a preservative, including meat, fish and cheese, as
a result of nitrosation of piperidine in the presence of nitrite. N-Nitrosopiperidine
is reasonably anticipated to be a human carcinogen. (NCI05);
