CAS 32598-13-3: PCB 77

Description: PCB 77, or 3,3',4,4'-tetrachlorobiphenyl, is a member of the polychlorinated biphenyl (PCB) family, which consists of synthetic organic chemicals composed of biphenyl with multiple chlorine atoms attached. Characteristically, PCB 77 has a molecular formula that reflects its chlorinated structure, contributing to its hydrophobic nature and stability. This compound is typically a colorless to light yellow solid at room temperature and is known for its high thermal stability and resistance to degradation, making it persistent in the environment. PCB 77 is classified as a persistent organic pollutant (POP) due to its potential for bioaccumulation in the food chain and its long half-life in various environmental matrices. It has been associated with various adverse health effects, including endocrine disruption and potential carcinogenicity. Due to these properties, PCBs, including PCB 77, have been subject to regulatory restrictions and bans in many countries, particularly concerning their use in electrical equipment and other industrial applications.
