2,3',4,4',6-pentachlorobiphenyl

Description:

2,3',4,4',6-pentachlorobiphenyl, with the CAS number 56558-17-9, is a member of the polychlorinated biphenyl (PCB) family, which are synthetic organic chemicals known for their environmental persistence and potential toxicity. This compound consists of two biphenyl rings with five chlorine atoms substituted at specific positions, which significantly alters its physical and chemical properties. It is typically a solid at room temperature and exhibits low volatility. The presence of chlorine atoms enhances its hydrophobicity, making it poorly soluble in water but more soluble in organic solvents. 2,3',4,4',6-pentachlorobiphenyl is known for its stability and resistance to degradation, contributing to its accumulation in the environment and living organisms. Due to its potential health risks, including endocrine disruption and carcinogenic effects, its use has been heavily regulated or banned in many countries. Monitoring and remediation efforts are ongoing to address the environmental impact of PCBs, including this specific compound.
