2,3,4,6-tetrachlorophenol

2,3,4,6-tetrachlorophenol is an organochlorine compound with the molecular formula C6H2Cl4O and CAS number 58-90-2. This chemical substance belongs to the chlorinated phenol family, featuring four chlorine atoms attached to a phenol ring at positions 2, 3, 4, and 6. With a molecular weight of 231.9 g/mol, it is classified as a hazardous substance requiring careful handling due to its acute toxicity and environmental impact.

2,3,4,6-tetrachlorophenol typically appears as a crystalline solid at room temperature with a characteristic phenolic odor. The compound has limited water solubility but dissolves well in organic solvents such as alcohols and ethers. Its high chlorine content contributes to its stability and persistence in the environment. The molecular structure with four chlorine substituents affects its melting point, boiling point, and vapor pressure characteristics.

2,3,4,6-tetrachlorophenol is primarily used as an intermediate in chemical synthesis and as a precursor for manufacturing other chlorinated organic compounds. It finds applications in the production of pesticides, herbicides, and wood preservatives. The compound is also utilized in research and analytical chemistry as a reference standard. Its antimicrobial properties make it useful in certain industrial preservation applications where chemical stability is required.

2,3,4,6-tetrachlorophenol requires strict safety precautions due to its Acute Tox. 3 classification and irritant properties. Essential protective equipment includes chemical-resistant gloves, safety goggles, and protective clothing to prevent skin and eye contact. Work in well-ventilated areas or use fume hoods to avoid inhalation. Never eat, drink, or smoke when handling this substance. Wash hands thoroughly after use and ensure emergency eyewash stations are accessible.

2,3,4,6-tetrachlorophenol should be stored in tightly sealed, original containers in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Keep containers protected from light and moisture to prevent degradation. Store separately from strong oxidizing agents, bases, and metals. Ensure storage areas are equipped with appropriate spill containment measures and maintain proper inventory records due to its hazardous classification.

2,3,4,6-tetrachlorophenol contact requires immediate first aid measures. For skin contact, remove contaminated clothing and rinse affected area with plenty of 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. Always consult a physician after any significant exposure.

2,3,4,6-tetrachlorophenol disposal must comply with local and European waste regulations due to its hazardous classification. The substance cannot be disposed of in regular waste streams and requires treatment by licensed hazardous waste disposal companies. Incineration at high temperatures in approved facilities is typically the preferred disposal method. Empty containers should also be treated as hazardous waste. Consult local authorities for specific disposal requirements and authorized waste handlers.

2,3,4,6-tetrachlorophenol is classified under ADR Class 6.1 (toxic substances) Packing Group III for transportation. Packages must display appropriate hazard labels including GHS06 and GHS09 pictograms with 'Danger' signal word. Transport documents must include proper shipping names, UN numbers, and hazard classifications. Vehicles must carry appropriate emergency equipment and drivers require ADR training. Ensure packages are properly sealed and protected from damage during transit.

2,3,4,6-tetrachlorophenol is subject to European REACH regulation and CLP classification requirements. The substance displays GHS06 and GHS09 pictograms indicating acute toxicity and environmental hazards. It carries multiple hazard classifications including Acute Tox. 3, skin and eye irritation, and aquatic toxicity. While not currently listed as an SVHC, it requires safety data sheets, proper labeling, and compliance with occupational exposure limits where established by member states.
