4-chlorophenol

4-chlorophenol is an organic chemical compound with the molecular formula C6H5ClO and CAS number 106-48-9. It belongs to the family of chlorinated phenols, featuring a benzene ring with both a hydroxyl group (-OH) and a chlorine atom attached at the para position. With a molecular weight of 128.55 g/mol, this compound is classified as moderately toxic and poses environmental hazards, particularly to aquatic ecosystems.

4-chlorophenol is typically a white to pale yellow crystalline solid at room temperature with a characteristic phenolic odor. It has moderate solubility in water and is readily soluble in organic solvents such as ethanol and acetone. The compound exhibits typical phenolic properties including weak acidity and the ability to form hydrogen bonds. Its chlorinated structure provides increased stability compared to unsubstituted phenol.

4-chlorophenol serves as an important intermediate in the production of pharmaceuticals, pesticides, and dyes. It is commonly used in the synthesis of herbicides and fungicides, particularly in agricultural applications. The compound also finds use in the manufacturing of polymers, resins, and various organic chemicals. Additionally, it serves as a precursor for the production of other chlorinated aromatic compounds in industrial chemistry.

4-chlorophenol requires careful handling due to its Acute Tox. 4 classification across multiple exposure routes. Essential personal protective equipment includes chemical-resistant gloves, safety goggles, and protective clothing to prevent skin contact. Work should be conducted in well-ventilated areas or under fume extraction systems. Avoid inhalation of dust or vapors, and ensure no eating, drinking, or smoking in work areas. Regular hand washing and proper hygiene practices are mandatory.

4-chlorophenol should be stored in a cool, dry, well-ventilated area away from direct sunlight and heat sources. Keep containers tightly sealed to prevent moisture absorption and contamination. Store away from strong oxidizing agents, strong bases, and incompatible materials. Ensure storage areas are equipped with appropriate spill containment measures and emergency response equipment. Maintain proper inventory rotation and regular container inspection for integrity.

Immediate action is required for any contact with 4-chlorophenol. For skin contact, remove contaminated clothing and wash affected area thoroughly with soap and water for at least 15 minutes. In case of eye contact, flush immediately with clean water for 15-20 minutes while holding eyelids open. If inhaled, move to fresh air immediately. For ingestion, do not induce vomiting and seek medical attention promptly. Always consult a physician after any significant exposure.

4-chlorophenol waste must be disposed of as hazardous waste in accordance with local and European regulations. It cannot be disposed of in regular waste streams or sewage systems due to its toxicity and environmental persistence. Contact licensed hazardous waste disposal companies for proper treatment, which typically involves high-temperature incineration or specialized chemical treatment. Maintain proper documentation and waste tracking records as required by applicable regulations.

4-chlorophenol is classified under ADR as Class 6.1 (toxic substances), Packing Group III, indicating moderate toxicity during transport. It must be packaged in UN-approved containers with appropriate labeling including GHS07 and GHS09 pictograms and 'Warning' signal word. Transport documentation must include proper shipping names, hazard classes, and emergency response information. Only trained personnel should handle transportation, and vehicles must carry appropriate emergency equipment.

4-chlorophenol is subject to various European chemical regulations including REACH registration requirements and CLP classification standards. It is not currently listed as a Substance of Very High Concern (SVHC), but its Aquatic Chronic 2 classification means it requires careful environmental risk assessment. Users must comply with occupational exposure limits, waste disposal regulations, and transport requirements. Regular safety data sheet updates and worker training are mandatory compliance elements.

4-chlorophenol is available through OYSI, a European distributor of technical chemicals, serving customers across the continent with reliable supply chains. As a specialized chemical requiring proper handling and documentation, it's essential to source from reputable distributors who ensure product quality, regulatory compliance, and proper safety documentation. Professional distributors provide technical support, safety data sheets, and guidance on handling requirements for industrial applications.
