CAS 32774-16-6: 3,3′,4,4′,5,5′-Hexachlorobiphenyl
Description:3,3′,4,4′,5,5′-Hexachlorobiphenyl, commonly referred to as PCB 153, is a member of the polychlorinated biphenyl (PCB) family, characterized by its biphenyl structure with six chlorine atoms substituted at the 3, 3', 4, 4', 5, and 5' positions. This compound is a colorless to light yellow solid at room temperature and is known for its hydrophobic nature, making it poorly soluble in water but soluble in organic solvents. PCB 153 is persistent in the environment, exhibiting resistance to degradation, which contributes to its bioaccumulation in the food chain. It has been associated with various adverse health effects, including endocrine disruption and potential carcinogenicity. Due to its environmental persistence and toxicity, the use of PCBs, including PCB 153, has been largely banned or restricted in many countries. Analytical methods such as gas chromatography-mass spectrometry (GC-MS) are commonly employed to detect and quantify this compound in environmental samples.
