Potassium 1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,8-heptadecafluorooctane-1-sulfonate

Potassium 1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,8-heptadecafluorooctane-1-sulfonate is a perfluorinated compound (PFC) belonging to the perfluorooctane sulfonate (PFOS) family. With the molecular formula C8F17KO3S and CAS number 2795-39-3, this potassium salt has a molecular weight of 538.22 g/mol. It is classified as a highly persistent organic pollutant with significant health and environmental concerns, including carcinogenic and reproductive toxicity properties.

Potassium PFOS is typically a white to off-white crystalline powder at room temperature. Due to its perfluorinated structure, it exhibits exceptional chemical and thermal stability, resistance to degradation, and unique surfactant properties. The compound is highly soluble in water and polar solvents, while being relatively insoluble in non-polar organic solvents. Its fluorinated carbon chain provides hydrophobic and lipophobic characteristics, making it extremely persistent in environmental and biological systems.

Potassium PFOS was historically used as a surfactant in various industrial applications including metal plating, semiconductor manufacturing, and as a component in firefighting foams. However, due to its classification as a persistent organic pollutant and severe restrictions under international regulations, its commercial use is now heavily limited. Current applications are restricted to essential uses where no suitable alternatives exist, primarily in specialized industrial processes under strict regulatory oversight.

Safe handling of potassium PFOS requires comprehensive personal protective equipment including chemical-resistant gloves, safety goggles, and respiratory protection. Work must be conducted in well-ventilated areas or under fume extraction systems to prevent inhalation. Avoid skin and eye contact, and prevent ingestion. Use appropriate containment measures to prevent environmental release. Given its carcinogenic and reproductive toxicity classifications, minimize exposure duration and implement strict hygiene protocols including thorough handwashing after handling.

Potassium PFOS should be stored in tightly sealed, chemically compatible containers in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Maintain storage temperatures below 25°C and protect from moisture. Ensure containers are properly labeled and store separately from food, feed, and drinking water. Implement secondary containment measures to prevent environmental contamination in case of spills. Access should be restricted to authorized personnel only due to its hazardous nature.

Immediate decontamination is essential following any contact with potassium PFOS. For skin contact, remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. In case of eye contact, flush immediately with clean water for 15-20 minutes. If inhaled, move to fresh air immediately. If ingested, do not induce vomiting and seek immediate medical attention. Contact emergency services and provide safety data sheet information to medical personnel.

Disposal of potassium PFOS must comply with strict hazardous waste regulations and cannot be performed through conventional waste streams. The substance requires specialized high-temperature incineration at authorized hazardous waste facilities equipped to handle perfluorinated compounds. Contact licensed hazardous waste disposal companies for proper collection and treatment. Document all disposal activities for regulatory compliance. Under no circumstances should this material be released to sewers, groundwater, or general waste systems due to its persistent and bioaccumulative nature.

Transportation of potassium PFOS is regulated under ADR classification 6.1 (toxic substances), Packing Group III. Packages must be properly labeled with appropriate hazard placards and transported by certified carriers trained in hazardous materials handling. Use approved packaging materials that meet UN specification requirements. Transport documentation must include proper shipping names, hazard classes, and emergency response information. Ensure vehicles are equipped with appropriate spill containment materials and emergency contact information during transit.

Potassium PFOS is subject to extensive international regulations including the Stockholm Convention on Persistent Organic Pollutants, EU REACH regulation, and various national restrictions. Its use is severely restricted or banned in many jurisdictions due to its classification as a persistent organic pollutant. Import/export may require special permits and notifications. Companies must comply with registration, evaluation, and authorization requirements. Specific restrictions apply to manufacturing, placing on the market, and use in various applications across different regions.
