It is not used for any commercial applications and is used only for research purposes, principally as an internal standard in the chemical analysis of nitroarenes. The primary route of potential human exposure to 6-nitrochrysene is inhalation. Low concentrations of this chemical have been found in ambient airborne particulates. It is reasonably anticipated to be a human carcinogen. (NCI05)"}]
