Product Name: Tetraethylammonium Perfluorooctanesulfonate
Chemical Formula: C12H20F17NO3S
Common Uses: Laboratory research, specialized chemical synthesis
Appearance: White crystalline powder or solid, depending on grade and source
Odor: Generally odorless, but some may notice faint chemical scent upon handling
Health Risks: Toxic if ingested or inhaled, skin and eye contact may lead to irritation or burns, long-term exposure can damage organs based on animal data for related fluoroalkyl compounds
Environmental Risks: Persistent in water and soil, bioaccumulation has been tracked for related PFOS-based chemicals, and aquatic toxicity data shows significant threat to fish and amphibians
Routes of Exposure: Inhalation, skin absorption, ingestion
Symptoms: Nausea, headaches, respiratory irritation, skin reddening, significant eye pain and possible corneal injury observed in case reports for similar chemicals
Label Elements: Hazard pictograms required by most chemical hygiene programs, warnings for toxic, reactive, and environmental hazard
Main Ingredient: Tetraethylammonium Perfluorooctanesulfonate
Chemical Family: Perfluorinated organosulfonic salts
Purity: Most research-grade samples top 95% purity
Impurities: Trace organic and inorganic salts, possible solvent residues from synthesis
Relevant Synonyms: TEA-PFOS, perfluorooctane sulfonate, tetraethylammonium salt
Inhalation: Move to fresh air, keep person calm, contact emergency services if symptoms linger
Skin Contact: Wash exposed area with soap and water immediately, remove contaminated clothing, seek medical attention for tissue irritation or burns
Eye Contact: Rinse eyes slowly and gently with water for at least 15 minutes, avoid rubbing, see medical help for any sustained pain or vision changes
Ingestion: Rinse mouth, do not induce vomiting, seek immediate medical care for any ingestion incident
Medical Attention: Facilities handling TEA-PFOS should keep eyewash stations and safety showers nearby due to risk of splashes
Suitable Extinguishing Media: Water spray, foam, dry chemical, or carbon dioxide works best for small fires
Hazardous Combustion Products: Thermal decomposition can release toxic gases including hydrogen fluoride, carbon oxides, and sulfur oxides
Special Protective Equipment: Firefighters should gear up with full protective suits and self-contained breathing apparatus
Firefighting Tips: Evacuate area, cool any containers with water from safe distance, avoid runoff into sewers or waterways to prevent chemical persistence
Personal Precautions: Evacuate unnecessary personnel, ventilate area, equip responders with gloves, goggles, and respirators
Spill Cleanup: Collect solid spills using non-sparking tools, place in sealed chemical waste containers, contain any dust created
Environmental Precautions: Block entry to drains and soil, because persistence in the environment piles up contamination expense over time
Decontamination: Wash surfaces with plenty of water and detergent, monitor area for residues since simple cleaning rarely removes all traces
Storage Conditions: Keep in cool, dry, and well-ventilated place, always away from oxidizers and incompatible chemicals
Handling Practices: Limit handling to trained personnel, wear protective equipment at all times, avoid dust formation and storage in areas with food or drink
Container Requirements: Use tightly closed original containers, label clearly, and monitor for leaks or cracks in packaging, especially after temperature swings
Occupational Exposure: Only open or transfer materials in designated chemical fume hoods or gloveboxes to keep vapors and dusts at bay
Recommended Engineering Controls: Chemical fume hoods and ventilated enclosures help drop airborne dust and vapor risks
Respiratory Protection: NIOSH/MSHA-approved respirators for powder work or if dusts or vapors may escape general ventilation
Skin Protection: Chemical-resistant gloves—such as nitrile or PVA—along with full lab coats and closed-toe shoes
Eye and Face Protection: Safety goggles or face shields, because just ordinary glasses won’t cut it with toxic fine powders
Hygiene: Wash hands and face after handling, change out of work clothes before eating or drinking, strictly no food in working areas
Physical State: Solid
Color: White to off-white, depending on impurities
Melting Point: Near 150–160°C, thermal decomposition above that
Solubility: Highly soluble in water, some miscibility with organic solvents
Boiling Point: Decomposes upon heating before reaching boiling
Odor: Faint chemical scent for most samples
pH: Acidic to mildly neutral in aqueous solution, based on salt form
Flash Point: Not flammable in standard settings, but decomposition risk with strong heating
Chemical Stability: Stable under recommended storage, but decomposition risk with high temperatures or strong acids
Reactivity: Incompatible with strong oxidizing agents, acids, and alkali metals
Hazardous Decomposition: Hydrogen fluoride, sulfur oxides, perfluorinated carbon fragments all pose inhalation threats
Polymerization: No expected polymerization under reasonable laboratory conditions
Acute Toxicity: Ingesting or inhaling small amounts can disrupt nervous system function, liver, and kidneys in animal studies
Chronic Exposure Risks: Liver and thyroid changes, developmental toxicity, increased risk of certain cancers based on long-term studies of related PFOS chemicals
Routes of Entry: Mainly through skin, eyes, ingestion, and inhalation
Irritation: Skin and mucous membrane irritation
Carcinogenicity: IARC and EPA track concern for perfluorinated organosulfonates in general; strong data points to probable human carcinogen status for PFOS relatives
Persistence: Perfluorooctanesulfonate structure does not break down easily, so it stays in water, soil, and animal tissue for decades
Bioaccumulation: Fish and mammals accumulate these compounds, impacting food chains in and near contaminated water bodies
Ecotoxicity: Proven risks to aquatic species, amphibians, and even birds as tracked by monitoring campaigns near PFOS contamination sites
Transport in Environment: Leaches rapidly through water, spreads through atmospheric transport in dust
Impacts: Ecosystem stress, loss of biodiversity, and poisoned drinking water in affected regions
Waste Treatment: High-temperature incineration is one of the few effective disposal methods, common landfill disposal leads to later leaching
Contaminated Packaging: Clean thoroughly before landfill or follow incineration protocols, never reuse packaging for food or general waste
Environmental Release: Strict controls in most countries prevent dumping, ongoing monitoring essential to keep up with persistence risk
Regulation: Most labs work with specialized hazardous waste contractors for disposal to guarantee compliance and limit local ecosystem risk
Shipping Classification: Most countries require shipping as hazardous chemical, detailed MSDS copies accompany every consignment
Container Requirements: Select high-integrity, sealed packaging, and strong outer containers
Labeling: Clearly label all containers with hazard pictograms, transport codes, and chemical name
Spill Response: Emergency plans call for containment kits and immediate notifications if leaks or spills occur during transit
Local and International Lists: Many countries include perfluorooctanesulfonates on their priority pollutant lists, subjected to restrictions in EU, US, Japan, and Canada
Worker Protection Laws: Occupational exposure standards enforce limits in labs and industrial facilities, require reporting of incidents
Environmental Regulations: Strict limits on wastewater release and ongoing groundwater monitoring in many jurisdictions
Ongoing Research: Regulatory agencies and scientific groups review new data and move to tighten restrictions as more facts about bioaccumulation and toxicity come out
