| Description | Benzo[a]pyrene-7,8-diol, also known as BP-7,8 diol, 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. Benzo[a]pyrene-7,8-diol is an extremely weak basic (essentially neutral) compound (based on its pKa). Benzo[a]pyrene-7,8-diol exists in all living organisms, ranging from bacteria to humans. These are compounds containing a pyrene moiety, which consists four fused benzene rings, resulting in a flat aromatic system. |
