Chrysene

Description:

Chrysene is a polycyclic aromatic hydrocarbon (PAH) characterized by its four fused benzene rings, resulting in a planar, aromatic structure. It appears as a yellowish crystalline solid at room temperature and is insoluble in water but soluble in organic solvents such as benzene and chloroform. Chrysene has a molecular formula of C18H12 and a molecular weight of approximately 228.3 g/mol. It is known for its fluorescence properties, making it useful in various applications, including organic electronics and as a fluorescent probe in biochemical studies. Chrysene is also a component of coal tar and can be found in fossil fuels, leading to its presence in environmental samples. However, it is important to note that chrysene is considered a potential carcinogen, and exposure to it should be minimized. Its stability under heat and light makes it a subject of study in environmental chemistry, particularly concerning its persistence and transformation in the environment.

Benzo[a]phenanthrene

CAS: 218-01-9

Benzo[a]phenanthrene is a polycyclic aromatic hydrocarbon that is found in petroleum and coal tar. It has been shown to be a potent inducer of enzymes involved in the detoxification of xenobiotics, such as chrysene-inducible cytochrome P450 1A1 (CYP1A1), s-phenylmercapturic acid-inducible cytochrome P450 2E1 (CYP2E1), and benzo[a]pyrene-inducible glutathione S-transferase (GST). The optimum concentration for benzo[a]phenanthrene is determined by measuring the amount of enzyme activity in rat liver microsomes following the addition of benzo[a]phenanthrene. A fluorescence detector can be used to measure the fluorescence emission from benzo[a]phenanthrene at an excitation wavelength of 300 nm and an emission wavelength of 400 nm.
