2,2',4,5-tetrabromobiphenyl

Description:

2,2',4,5-tetrabromobiphenyl is a synthetic organic compound belonging to the class of brominated biphenyls, characterized by the presence of four bromine atoms attached to a biphenyl structure. This compound is typically a white to off-white solid at room temperature and is insoluble in water but soluble in organic solvents such as acetone and chloroform. It is primarily used as a flame retardant in various materials, including plastics and textiles, due to its ability to inhibit combustion. The presence of multiple bromine atoms enhances its thermal stability and reduces flammability. However, 2,2',4,5-tetrabromobiphenyl is also associated with environmental and health concerns, as it can persist in the environment and bioaccumulate in living organisms. Its potential toxicity and endocrine-disrupting properties have led to increased scrutiny and regulation in many regions. Proper handling and disposal are essential to mitigate risks associated with exposure to this compound.

Phenobarbital is a barbiturate that has been used as an anticonvulsant and sedative since the 1920s. It is metabolized by the liver cytochrome P450 enzyme CYP1A2, which converts it to its active form, phenobarbital-10,11-epoxide. Phenobarbital is excreted in the urine unchanged or as glucuronide and sulfate conjugates. The average age of people taking phenobarbital is 47 years old. The average total daily dose of phenobarbital is 1.8 mg/kg body weight (or 178 mg). The drug has a low risk of toxicity because it is not very toxic and has a low therapeutic index. Phenobarbital also increases the level of cytochrome P450 enzymes in the liver, which can lead to drug interactions with other drugs metabolized by these enzymes.
