2,4,6-trichlorophenol

2,4,6-trichlorophenol is an organochlorine compound with the molecular formula C6H3Cl3O and CAS number 88-06-2. This chemical substance has a molecular weight of 197.4 g/mol and belongs to the phenol family with three chlorine atoms substituted at positions 2, 4, and 6 on the benzene ring. It is classified as a hazardous substance with carcinogenic, toxic, irritating, and environmentally harmful properties according to CLP regulation.

2,4,6-trichlorophenol is typically a crystalline solid at room temperature with a characteristic phenolic odor. It appears as white to pale yellow crystals and has limited solubility in water but dissolves well in organic solvents like alcohols and ethers. The compound has a melting point around 69°C and is relatively stable under normal conditions. Its chlorinated structure makes it persistent in the environment and resistant to biodegradation.

2,4,6-trichlorophenol is primarily used as an intermediate in the synthesis of pesticides, fungicides, and herbicides. It serves as a precursor in the production of other chlorinated organic compounds and can be used in wood preservation treatments. The compound also finds applications in the manufacturing of dyes, pharmaceuticals, and specialty chemicals. Due to its antimicrobial properties, it may be used in certain disinfectant formulations, though its use is increasingly restricted due to environmental and health concerns.

2,4,6-trichlorophenol requires careful handling with appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and respiratory protection when necessary. Work should be conducted in well-ventilated areas or under fume extraction systems to minimize inhalation exposure. Avoid skin and eye contact, and prevent ingestion. Use non-sparking tools and equipment, and ensure proper grounding to prevent static electricity buildup. Always follow good industrial hygiene practices and wash hands thoroughly after handling.

2,4,6-trichlorophenol should be stored in tightly sealed containers in a cool, dry, and well-ventilated area away from direct sunlight and heat sources. Keep containers away from incompatible materials such as strong oxidizers and bases. Storage areas should be equipped with appropriate spill containment measures and fire suppression systems. Maintain storage temperatures below 25°C when possible, and ensure containers are properly labeled according to CLP requirements. Regular inspection of storage conditions and container integrity is essential.

In case of skin contact with 2,4,6-trichlorophenol, 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 15-20 minutes and remove contact lenses if easily removable. If inhaled, move the person to fresh air immediately. In case of ingestion, do not induce vomiting and seek immediate medical attention. Always consult a physician if symptoms persist or in case of significant exposure.

2,4,6-trichlorophenol disposal must comply with local and national hazardous waste regulations as it is classified as dangerous waste. The substance should never be discharged into sewers, waterways, or soil due to its environmental toxicity. Disposal should be carried out through licensed hazardous waste treatment facilities capable of handling chlorinated organic compounds. Incineration at high temperatures in specialized facilities is typically the preferred disposal method. Always consult local environmental authorities for specific disposal requirements and approved waste management companies.

2,4,6-trichlorophenol is classified under ADR as Class 6.1 (Toxic substances), Packing Group III, indicating moderate toxicity for transport purposes. Transportation must comply with ADR regulations including proper packaging, labeling, and documentation requirements. Vehicles must carry appropriate placarding and emergency response information. Drivers require ADR certification for Class 6.1 substances. Packaging must meet UN specification standards and be properly sealed and labeled with the correct shipping name and hazard labels.

2,4,6-trichlorophenol is subject to various regulatory frameworks including REACH registration requirements for manufacture or import above one tonne per year. Under CLP regulation, it must be classified and labeled according to its hazard profile with appropriate warning pictograms (GHS07, GHS08, GHS09). The substance may be subject to restrictions under various national and EU regulations due to its carcinogenic and environmental properties. Users must comply with occupational exposure limits and environmental discharge restrictions where applicable.
