What is pyrene used for?
Like most PAHs, pyrene is used to make dyes, plastics and pesticides. It has also been used to make another PAH called benzo(a)pyrene.
What is pyrene soluble in?
145 to 148 °C (293 to 298 °F; 418 to 421 K) Boiling point. 404 °C (759 °F; 677 K) Solubility in water. 0.146 mg/L.
Is pyrene soluble in methanol?
Solubility of pyrene, 1-AP, and 1-HP in methanol, DMF, and DMSO. It is known that pyrene’s solubility in water is 0.64 – 0.73 μM/L [27, 28]. Although it is not available, a much better water solubility for 1-AP and 1-HP is expected due to the presence of a polar amino or hydroxy group, respectively.

Is pyrene harmful to humans?
Benzo[a]pyrene is a probable cancer-causing agent in humans. There is some evidence that it causes skin, lung, and bladder cancer in humans and in animals. If benzo(a)pyrene is on your skin when you are being exposed to sunlight or ultraviolet light, the risk of skin cancer is greater.
Is pyrene a fluorescent?
Pyrene is a fluorescent probe whose spectrum is sensitive to the polarity of its environment. The ratio of the intensities between the third and the first vibronic components of the pyrene emission spectrum (bands I at 373 nm and III at 385 nm) (Fig. 2), r = III/I, is a measure of the local polarity.
Is pyrene organic or inorganic?
|Description||belongs to the class of organic compounds known as pyrenes. Pyrenes are compounds containing a pyrene moiety, which consists four fused benzene rings, resulting in a flat aromatic system.|
Where is pyrene found?
Pyrene is released naturally from the burning of wood, gasoline exhaust, and cigarette smoke. Pyrene is a natural component of coal tar and asphalt. Other sources of pyrene can include brightening agents and dyes, plastics, and pesticides.
What is benzopyrene used for?
There are indications that benzo[a]pyrene diol epoxide specifically targets the protective p53 gene. This gene is a transcription factor that regulates the cell cycle and hence functions as a tumor suppressor.
What does benzopyrene do to the body?
Benzo(a)pyrene can cause a skin rash, a burning feeling, skin color changes, warts, and bronchitis. It may also cause cancer. It is a type of polycyclic aromatic hydrocarbon. Also called 3,4-benzpyrene.
What does pyrene mean?

|Solubility in water||0.2 to 6.2 μg/L|
|Magnetic susceptibility (χ)||-135.7·10−6 cm3/mol|
Is benzopyrene a carcinogen?
The substance with the formula C20H12 is one of the benzopyrenes, formed by a benzene ring fused to pyrene. Its diol epoxide metabolites (more commonly known as BPDE) react with and bind to DNA, resulting in mutations and eventually cancer. It is listed as a Group 1 carcinogen by the IARC.
Is benzopyrene a cigarette?
Cigarette smoke is a known source of exposure to carcinogenic polycyclic aromatic hydrocarbons (PAHs), especially benzo[a]pyrene (BaP).
Where can benzopyrene be found?
It is found in car exhaust, smoke from wood fires, tobacco, oil and gas products, charred or grilled foods, and other sources.
What is a benzopyrene used for?
Benzo[a]pyrene is an ortho- and peri-fused polycyclic arene consisting of five fused benzene rings. It has a role as a carcinogenic agent and a mouse metabolite.
What does benzopyrene do to your body?
It is found in car exhaust, smoke from wood fires, tobacco, oil and gas products, charred or grilled foods, and other sources. It may also be found in water and soil. Benzo(a)pyrene can cause a skin rash, a burning feeling, skin color changes, warts, and bronchitis. It may also cause cancer.
Is pyrene a carcinogen?
The PAH prototype benzo[a]pyrene (B[a]P), an AhR ligand, exhibits a strong carcinogenic potential and it is classified as a carcinogen to humans by the International Agency for Research on Cancer (IARC).
Where can you find benzopyrene?
A chemical that comes from certain substances when they are not burned completely. It is found in car exhaust, smoke from wood fires, tobacco, oil and gas products, charred or grilled foods, and other sources. It may also be found in water and soil.
