PCB 121

Description:

PCB 121, or polychlorinated biphenyl 121, is a member of the polychlorinated biphenyl (PCB) family, which consists of synthetic organic chemicals with varying degrees of chlorination. With the CAS number 56558-18-0, PCB 121 is characterized by its biphenyl structure, where two benzene rings are connected by a single bond, and it contains multiple chlorine atoms attached to the rings. Specifically, PCB 121 has a total of five chlorine atoms, which significantly influence its chemical properties, including its hydrophobicity and stability. This compound is typically colorless to light yellow and is known for its high thermal stability and resistance to degradation, making it useful in various industrial applications, such as electrical equipment and heat transfer fluids. However, PCBs, including PCB 121, are recognized for their environmental persistence and potential health risks, including carcinogenic effects and endocrine disruption. Due to these concerns, the production and use of PCBs have been largely banned or restricted in many countries.
