Sodium 2,3,4,5,6-pentachlorophenolate

Sodium 2,3,4,5,6-pentachlorophenolate is the sodium salt of pentachlorophenol, a highly chlorinated aromatic compound with the molecular formula C6Cl5NaO. This chemical substance has a molecular weight of 288.3 g/mol and is classified as a hazardous material with significant toxicity concerns. It is identified by CAS number 131-52-2 and carries multiple danger classifications including carcinogenicity category 2 and acute toxicity warnings, making it a controlled industrial chemical requiring specialized handling procedures.

Sodium 2,3,4,5,6-pentachlorophenolate typically appears as a white to off-white crystalline solid at room temperature. As a sodium salt of a phenolic compound, it exhibits good water solubility compared to its parent acid form. The compound has a molecular weight of 288.3 g/mol and contains five chlorine atoms attached to the benzene ring, contributing to its chemical stability and biological persistence. Its high chlorine content influences both its physical properties and environmental behavior.

Sodium 2,3,4,5,6-pentachlorophenolate is primarily used as a biocide and preservative in industrial applications. Its strong antimicrobial properties make it effective for wood preservation, leather treatment, and as an industrial disinfectant. Due to its high toxicity and environmental persistence, its use has become increasingly restricted in many applications. Current uses are mainly limited to specific industrial processes where alternative compounds cannot provide equivalent performance under controlled conditions.

Sodium 2,3,4,5,6-pentachlorophenolate must be handled with extreme caution due to its acute toxicity and carcinogenic potential. Essential personal protective equipment includes chemical-resistant gloves, safety goggles, respiratory protection, and full protective clothing. Work should be conducted in well-ventilated areas or under fume extraction systems. Avoid skin contact, inhalation, and ingestion. Emergency washing facilities must be readily available, and personnel should be trained in proper handling procedures and emergency response protocols.

Sodium 2,3,4,5,6-pentachlorophenolate should be stored in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Keep containers tightly sealed to prevent moisture absorption and contamination. Store separately from food, beverages, and animal feed. The storage area should be secure, clearly labeled, and accessible only to trained personnel. Ensure compliance with local regulations regarding hazardous chemical storage and maintain appropriate inventory records for regulatory reporting requirements.

Immediate action is critical in case of contact with sodium 2,3,4,5,6-pentachlorophenolate due to its high toxicity. For skin contact, immediately remove contaminated clothing and flush the affected area with plenty of water for at least 15 minutes. In case of eye contact, rinse thoroughly with water and seek immediate medical attention. If inhaled, move the person to fresh air and provide respiratory support if needed. For ingestion, do not induce vomiting and seek emergency medical care immediately while providing the safety data sheet.

Sodium 2,3,4,5,6-pentachlorophenolate must be disposed of as hazardous waste through licensed waste management facilities due to its toxicity and environmental persistence. Incineration at high temperatures in specialized facilities is typically the preferred disposal method. Never discharge into sewers, waterways, or ordinary waste streams. Contact authorized hazardous waste contractors for proper collection and disposal. Maintain detailed waste disposal records for regulatory compliance and ensure all disposal activities meet local and national environmental regulations.

Sodium 2,3,4,5,6-pentachlorophenolate is classified under ADR Class 6.1 (toxic substances) with Packing Group II, indicating significant transportation hazards. Shipments must comply with dangerous goods regulations including proper packaging, labeling with appropriate hazard symbols, and documentation. Transport vehicles require placarding and drivers need hazardous materials certification. Emergency response information must accompany shipments, and specific routing restrictions may apply. Only use approved packaging and work with carriers experienced in hazardous chemical transportation.

Sodium 2,3,4,5,6-pentachlorophenolate is subject to extensive regulatory control under REACH, CLP, and national chemical safety legislation. Its classification as Carcinogenic Category 2 and highly toxic substance triggers strict registration, authorization, and reporting requirements. While not currently listed as a Substance of Very High Concern (SVHC), its hazard profile means it faces ongoing regulatory scrutiny and potential restrictions. Users must comply with occupational exposure limits, environmental discharge controls, and specific industry regulations governing its use and handling.

Sodium 2,3,4,5,6-pentachlorophenolate is available through specialized chemical distributors like OYSI, a European distributor of technical chemicals. Due to its hazardous nature and regulatory restrictions, this compound is only supplied to qualified industrial users with appropriate licenses and safety capabilities. Purchasers must demonstrate legitimate use, proper handling facilities, and regulatory compliance. OYSI can provide technical support, safety documentation, and ensure proper packaging and transportation according to European chemical distribution standards.
