CAS 33979-03-2: PCB 155

Description: PCB 155, or polychlorinated biphenyl 155, is a member of the polychlorinated biphenyl (PCB) family, which consists of synthetic organic chemicals with varying degrees of chlorination. Characterized by its complex structure, PCB 155 contains multiple chlorine atoms attached to biphenyl, influencing its physical and chemical properties. It is typically a colorless to light yellow solid or liquid, depending on its formulation and purity. PCBs, including PCB 155, are known for their hydrophobic nature, low volatility, and thermal stability, making them resistant to degradation in the environment. However, they are also persistent organic pollutants, posing significant environmental and health risks due to their bioaccumulation in the food chain and potential endocrine-disrupting effects. PCB 155 has been used in various industrial applications, including electrical equipment and heat transfer fluids, although its production and use have been largely banned or restricted in many countries due to environmental concerns. Proper handling and disposal of PCB-containing materials are crucial to mitigate their impact on human health and ecosystems.
