Indeno[1,2,3-cd]pyrene

Indeno[1,2,3-cd]pyrene (IP) is a polycyclic aromatic hydrocarbon (PAH) that consists of six fused benzene rings and a five-membered ring. It has the chemical formula C22H12 and a molecular weight of 276.33 g/mol.

IP 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.

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