4-tert-butylphenol

4-tert-butylphenol is an organic chemical compound with the molecular formula C10H14O and CAS number 98-54-4. It belongs to the phenol family, characterized by a phenol ring substituted with a tert-butyl group at the para position. This compound has a molecular weight of 150.22 g/mol and is classified as a hazardous substance requiring careful handling due to its reproductive toxicity, skin and eye irritation properties, and environmental impact on aquatic life.

4-tert-butylphenol typically appears as white to pale yellow crystalline solid at room temperature with a characteristic phenolic odor. It has moderate solubility in organic solvents like alcohols and ethers but limited solubility in water. The compound exhibits typical phenolic chemical behavior, including reactivity with bases and oxidizing agents. Its tert-butyl substitution provides steric hindrance that affects its reactivity compared to unsubstituted phenol, making it more stable under certain conditions.

4-tert-butylphenol serves primarily as an intermediate in chemical synthesis and industrial applications. It is commonly used in the production of antioxidants, particularly for rubber and plastic industries, where it helps prevent oxidative degradation. The compound also finds application in the manufacture of resins, adhesives, and coatings. Additionally, it serves as a building block for various specialty chemicals and can be used in research and development applications requiring phenolic compounds with specific structural properties.

4-tert-butylphenol requires careful handling with appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing to prevent skin and eye contact. Work should be conducted in well-ventilated areas or under fume hoods to avoid inhalation. Due to its reproductive toxicity classification (Repr. 2), pregnant workers should avoid exposure. Always wash hands thoroughly after handling and avoid eating, drinking, or smoking in work areas. Emergency eyewash stations and safety showers should be readily accessible.

4-tert-butylphenol should be stored in a cool, dry, well-ventilated area away from heat sources, direct sunlight, and incompatible materials. Keep containers tightly closed when not in use and store in original labeled containers. Avoid storage near strong oxidizing agents, strong bases, and sources of ignition. The storage area should be equipped with appropriate spill containment measures and restricted access. Regular inspection of containers for damage or leakage is recommended to maintain storage integrity and safety.

In case of skin contact with 4-tert-butylphenol, immediately remove contaminated clothing and wash the affected area with plenty of soap and water for at least 15 minutes. For eye contact, rinse immediately with clean water for at least 15 minutes while holding eyelids open. If inhaled, move the person to fresh air and seek medical attention if breathing difficulties occur. Remove contaminated clothing and wash before reuse. Seek immediate medical attention for any exposure, especially given the compound's hazardous classification.

4-tert-butylphenol must be disposed of as hazardous waste in accordance with local, national, and EU regulations. Contact licensed waste management companies for proper collection and treatment. Do not discharge to sewers, waterways, or soil due to its aquatic toxicity classification. Small quantities may require incineration at authorized high-temperature facilities. Always consult current waste classification codes and follow your local environmental authority guidelines. Maintain proper documentation for waste disposal tracking and compliance purposes.

4-tert-butylphenol is classified under ADR Class 9 (Miscellaneous dangerous goods), Packing Group III, indicating it poses moderate transport risks. Packages must be properly labeled with appropriate hazard symbols and shipping documentation must include correct technical names and classifications. Use approved packaging materials and ensure containers are secure and leak-proof. Drivers must carry appropriate transport documents and emergency response information. Follow ADR regulations for loading, segregation, and vehicle marking requirements during transportation.

4-tert-butylphenol is subject to various European regulations including REACH registration requirements for manufacture and import. Under CLP regulation, it must be classified and labeled according to its hazard properties with appropriate pictograms (GHS05, GHS08, GHS09) and danger signal word. While not currently listed as SVHC, its reproductive toxicity classification means it may face future regulatory scrutiny. Users must comply with occupational exposure limits and safety data sheet requirements for workplace protection and environmental compliance.
