PBB 77

Description:

PBB 77, or polybrominated biphenyl 77, is a member of the polybrominated biphenyl (PBB) family, which are synthetic organic compounds known for their flame-retardant properties. PBB 77 is characterized by its brominated structure, which enhances its stability and resistance to degradation. This compound is typically used in various industrial applications, including as a flame retardant in plastics and textiles. PBBs, including PBB 77, are known for their persistence in the environment and potential bioaccumulation in living organisms, raising concerns regarding their ecological and health impacts. They can disrupt endocrine functions and have been associated with various adverse health effects. Due to these concerns, the use of PBBs has been restricted or banned in many countries. PBB 77 is typically found in solid form and is insoluble in water, but it can dissolve in organic solvents. Its handling requires caution due to its potential toxicity and environmental persistence.
