CAS 50-32-8: Benzo[a]pyrene

Description: Benzo[a]pyrene (BaP) is a polycyclic aromatic hydrocarbon (PAH) characterized by its fused benzene rings, specifically consisting of five rings. It is a colorless to pale yellow solid at room temperature and is known for its high stability and hydrophobic nature, making it poorly soluble in water but soluble in organic solvents. BaP is primarily produced through incomplete combustion of organic materials, such as fossil fuels, tobacco, and grilled meats, and is commonly found in environmental pollutants, including air, soil, and water. It is recognized as a potent carcinogen, with the ability to form DNA adducts, leading to mutagenic effects. Due to its toxicological properties, BaP is subject to regulatory scrutiny and is monitored in various environmental and food safety contexts. Additionally, it has been studied for its potential effects on human health, particularly in relation to cancer risk, prompting ongoing research into its mechanisms of action and pathways of exposure.
