Documented Uses

• No commercial applications; Found in particulates in emissions from combustion, e.g., diesel exhausts; [NTP] Found in some carbon blacks and in emissions from diesel engines, kerosene heaters, and gas burners; [IARC]
• 1,8-Dinitropyrene has been reported to be a photosensitizer, increasing the spectral activity of bis-azide compounds with light. However, no evidence was found that 1,8-dinitropyrene is currently used commercially for this or other applications.
• Mixtures of 1,3-, 1,6- and 1,8-dinitropyrenes are produced by the nitration of pyrene, and 1,8-dinitropyrene has been isolated and purified from such preparations.
• Substances that increase the risk of NEOPLASMS in humans or animals. Both genotoxic chemicals, which affect DNA directly, and nongenotoxic chemicals, which induce neoplasms by other mechanism, are included.
• Chemical agents that increase the rate of genetic mutation by interfering with the function of nucleic acids. A clastogen is a specific mutagen that causes breaks in chromosomes.
• ... It has been reported that nitroreduction, the most important pathway of nitroarene toxification, occurs mainly in the liver and intestine. ... Red cells also possess the metabolic competence to reduce nitroarenes. In particular, 1,8-dinitropyrene, the nitroarene chosen as model compound, was reduced to the corresponding mono- and diamino-derivatives, 1-amino-8-nitropyrene and 1,8-diaminopyrene, by human lysate supplemented with cofactors.
