Cyclopenta(c,d)Pyrene

Cyclopenta[c,d]pyrene (CPP) is a polycyclic aromatic hydrocarbon (PAH) that consists of five fused benzene rings. It has the molecular formula C18H10 and a molecular weight of 226.28 g/mol.

CPP is formed during the incomplete combustion of organic matter and is found in coal tar, crude oil, and cigarette smoke. It is also used as a starting material in the synthesis of other organic compounds, such as dyes, pigments, and pharmaceuticals.

CPP is considered to be a potential human carcinogen by various regulatory agencies due to its mutagenic and genotoxic properties. Exposure to CPP has been linked to an increased risk of cancer, particularly lung and skin cancers. Therefore, appropriate safety precautions should be taken when handling CPP to minimize the potential risks to human health and the environment.
