2,4,5-trichlorophenol

2,4,5-trichlorophenol is an organochlorine compound with the molecular formula C6H3Cl3O and CAS number 95-95-4. This chlorinated phenol derivative has a molecular weight of 197.4 g/mol and consists of a benzene ring substituted with three chlorine atoms at positions 2, 4, and 5, plus one hydroxyl group. It is classified as a hazardous chemical requiring proper handling and storage procedures due to its toxicity and environmental impact.

2,4,5-trichlorophenol is typically a white to pale yellow crystalline solid at room temperature with a characteristic phenolic odor. It has limited water solubility but dissolves well in organic solvents such as alcohols, ethers, and aromatic hydrocarbons. The compound exhibits acidic properties due to its phenolic hydroxyl group and has relatively high stability under normal conditions, though it may decompose under extreme heat or alkaline conditions.

2,4,5-trichlorophenol is primarily used as an intermediate in the synthesis of other chemicals, including pesticides, herbicides, and fungicides. It serves as a precursor in pharmaceutical manufacturing and can be utilized in the production of specialized polymers and resins. The compound also finds applications in research and analytical chemistry as a reference standard. Its antimicrobial properties make it useful in certain industrial preservation applications.

2,4,5-trichlorophenol 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 extraction to avoid inhalation exposure. The compound is classified as Acute Tox. 4, Skin Irrit. 2, and Eye Irrit. 2, requiring adherence to safety protocols and emergency procedures to minimize health risks.

2,4,5-trichlorophenol should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from heat sources, direct sunlight, and incompatible materials. Keep containers upright and properly labeled according to GHS requirements with Warning signal word and appropriate pictograms (GHS07, GHS09). Store separately from strong bases, oxidizing agents, and reactive metals. Ensure storage area has appropriate spill containment and fire protection measures.

In case of skin contact with 2,4,5-trichlorophenol, immediately remove contaminated clothing and wash affected area thoroughly with soap and water for at least 15 minutes. For eye contact, flush immediately with clean water for 15 minutes while holding eyelids open. If inhaled, move 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 worsen.

2,4,5-trichlorophenol must be disposed of as hazardous waste through licensed waste management companies in compliance with local, national, and EU regulations. Due to its classification as Aquatic Acute 1 and Aquatic Chronic 1, it requires special handling to prevent environmental contamination. Contact authorized waste disposal facilities for proper collection and treatment. Never dispose of this substance through regular waste streams or discharge into sewers or water bodies.

2,4,5-trichlorophenol is classified under ADR as Class 6.1 (toxic substances), Packing Group III, requiring compliance with dangerous goods transportation regulations. Packages must be properly labeled, marked, and documented with appropriate shipping papers. Transport vehicles must carry emergency equipment and drivers need ADR certification. Ensure containers are leak-proof, properly secured, and segregated from incompatible materials during transport across European borders.

2,4,5-trichlorophenol is regulated under EU REACH and CLP regulations, requiring registration, classification, and labeling compliance. While not currently listed as an SVHC (Substance of Very High Concern), it must be handled according to its hazard classification with Warning signal word and GHS pictograms. Companies must maintain safety data sheets, implement risk management measures, and comply with notification requirements for industrial use and distribution.
