4-chlorophenol

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

4-chlorophenol appears as white to pale yellow crystalline solid at room temperature with a characteristic phenolic odor. It has a melting point of approximately 43°C and is moderately soluble in water. The compound is more soluble in organic solvents like alcohol and ether. It exhibits typical phenolic properties including weak acidity and can form salts with bases.

4-chlorophenol serves primarily as an intermediate in the synthesis of pharmaceuticals, pesticides, and dyes. It is used in the production of antiseptics, disinfectants, and preservatives. The compound also finds applications in the manufacture of herbicides and as a chemical intermediate for producing other chlorinated organic compounds in various industrial processes.

4-chlorophenol requires careful handling using appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. Work in well-ventilated areas or under fume hoods to avoid inhalation. The substance carries GHS07 and GHS09 pictograms with 'Warning' signal word, indicating moderate toxicity risks. Avoid skin and eye contact, and prevent environmental release.

4-chlorophenol should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from heat sources and direct sunlight. Keep away from incompatible materials such as strong oxidizing agents and bases. Storage areas should be equipped with appropriate spill containment measures and maintained at stable temperatures to prevent degradation or hazardous reactions.

In case of skin contact with 4-chlorophenol, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. For eye contact, rinse immediately with clean water for 15 minutes and seek medical attention. If inhaled, move to fresh air immediately. If ingested, do not induce vomiting and seek immediate medical care.

4-chlorophenol must be disposed of as hazardous waste in accordance with local and national regulations. The substance cannot be disposed of in regular waste streams due to its toxicity and environmental impact classification (Aquatic Chronic 2). Contact licensed waste disposal companies specialized in chemical waste treatment. Incineration at high temperatures in authorized facilities is typically the preferred disposal method.

4-chlorophenol is classified under ADR as Class 6.1 (toxic substances), Packing Group III for transport purposes. It requires appropriate hazardous materials packaging, labeling, and documentation during transportation. Vehicles must display proper placarding, and drivers need hazardous materials training certification. Transport should comply with international dangerous goods regulations and route restrictions may apply.

4-chlorophenol is subject to REACH regulation requiring registration for manufacture or import in the EU above certain tonnages. It falls under CLP classification showing Acute Tox. 4 and Aquatic Chronic 2 hazard classes. The substance is not currently listed as SVHC (Substance of Very High Concern), but users must comply with safety data sheet requirements and exposure limit regulations.

4-chlorophenol is available through OYSI, a European distributor specializing in technical chemicals. As an established chemical supplier, OYSI can provide this substance to qualified industrial customers with proper documentation and safety data sheets. Professional buyers should contact OYSI directly to discuss specific requirements, quantities, and delivery options across European markets while ensuring regulatory compliance.
