1,8-DINITROPYRENE Chemical Properties,Usage,Production

Chemical Properties

1,8-Dinitropyrene is a nitro-substituted polycyclic aromatic hydrocarbon that exists at room temperature as a yellow fluffy or light-brown crystalline solid (IARC 1989). It has a molecular weight of 292.3 and a melting point of over 300°C (HSDB 2009).

Uses

1,8-Dinitropyrene has been reported to be a photosensitizer; however,there is no evidence that it has ever been used commercially for this or any other purpose (IARC 1989). 1,8-Dinitropyrene is available for research purposes at a purity of at least 99% and in ¹⁴C- or ³H-labeled form at a radiochemical purity of at least 98%.

Uses

1,8-Dinitropyrene is one of the major mutagens found in contaminated sediments. Also a potential human carcinogen.

Definition

ChEBI: 1,8-Dinitropyrene is a member of pyrenes.

General Description

The photodecomposition of environmental contaminant, 1,8-dinitropyrene via exposure to light (≥ 310nm) either in DMSO, or following coating onto silica has been investigated. 1,8-Dinitropyrene is a potent mutagenic component of diesel exhaust and air pollutant.

Safety Profile

Confirmed carcinogen with experimental carcinogenic data. Human mutation data reported. When heated to decomposition it emits toxic fumes of NOx

Carcinogenicity

1,8-Dinitropyrene is reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in experimental animals.
