Introduction to 4-Bromophenol (CAS 106-41-2)
4-Bromophenol, also known as 4-bromophenolic acid, is an organic compound with the molecular formula C6H4BrO. It is a colorless solid that is soluble in water and organic solvents. This compound is widely used in the production of dyes, pharmaceuticals, and other chemicals. However, its use has raised concerns regarding its safety and environmental impact.
Physical and Chemical Properties
4-Bromophenol has a melting point of approximately 61-62°C and a boiling point of around 247-249°C. It is a weak acid with a pKa value of 8.5. The compound is highly reactive and can undergo various chemical transformations, including hydrolysis, oxidation, and substitution reactions. These properties make it a versatile chemical in industrial applications but also raise concerns about its potential hazards.
Health Hazards
Exposure to 4-Bromophenol can pose several health hazards. Inhalation of its vapors can cause respiratory irritation, coughing, and shortness of breath. Skin contact can lead to irritation, redness, and allergic reactions. Ingestion of the compound can cause gastrointestinal irritation, nausea, vomiting, and diarrhea. Long-term exposure to 4-Bromophenol has been associated with potential carcinogenic effects, although the evidence is not conclusive.
Environmental Effects
4-Bromophenol is considered a persistent organic pollutant (POP) due to its ability to remain in the environment for extended periods. Once released into the environment, it can accumulate in aquatic ecosystems, posing a threat to aquatic life. The compound can bioaccumulate in organisms, leading to higher concentrations in higher trophic levels. This bioaccumulation can have detrimental effects on the food chain and ecosystem health.
Regulatory Status
The regulatory status of 4-Bromophenol varies by country. In the United States, the Environmental Protection Agency (EPA) regulates the production, use, and disposal of the compound under the Toxic Substances Control Act (TSCA). In the European Union, the substance is listed under the REACH regulation, which requires companies to register and manage the risks associated with its use. These regulations aim to minimize the environmental and health risks associated with 4-Bromophenol.
Disposal Methods
Proper disposal of 4-Bromophenol is crucial to prevent environmental contamination. The compound should not be disposed of in regular waste streams. Instead, it should be handled as a hazardous waste and disposed of in accordance with local and national regulations. This may involve neutralizing the compound to reduce its toxicity or incinerating it in a controlled environment.
Conclusion
4-Bromophenol (CAS 106-41-2) is a chemical compound with significant safety and environmental concerns. Its physical and chemical properties, health hazards, environmental effects, regulatory status, and disposal methods all contribute to the need for careful management and control of its use. By understanding these aspects, industries and individuals can take appropriate precautions to mitigate the risks associated with 4-Bromophenol and ensure its safe and sustainable use.
