网页2016年1月22日 · Pyrene is a carcinogenic agent and is absorbed by the skin. It is a skin irritant, a suspected mutagen, and an equivocal tumor-causing agent. Workers exposed to 3 to 5 mg/m3 of pyrene exhibited some teratogenic effects. Pyrene is a polycyclic aromatic hydrocarbon (PAH). The acute toxicity of pure PAHs appears low when administered …
Pyrene | Formula, Properties & Application
网页Pyrene is a crystalline solid at room temperature, and its crystals exhibit a characteristic bluish fluorescence under ultraviolet (UV) light. This property has been put to practical use in many analytical applications. It is insoluble in water but dissolves readily in many organic solvents, including toluene and benzene.

Pyrene - chemeurope.com
网页Pyrene is a polycyclic aromatic hydrocarbon (PAH) consisting of four fused benzene rings, resulting in a large, flat aromatic system. It is the smallest peri-fused polycyclic aromatic hydrocarbon - one where the rings are fused through more than one face. It forms during incomplete combustion of organic material and therefore can be isolated from coal tar …
网页Pyrene is one of a group of chemicals called polycyclic aromatic hydrocarbons, PAHs for short. PAHs are often found together in groups of two or more. They can exist in over 100 different combinations but the most common are treated as a group of 15. PAHs are found naturally in the environment but they can also be man-made.
