CAS Number: 944890-45-1
Formula: C19H39F6NO6P S2
Concentration Range: Greater than 95% in standard supplier products
Impurities: Trace contaminants from manufacturing cannot be ruled out, including residual phosphonium or bis(trifluoromethanesulfonyl)imide salts.
Inhalation: Move individual outside, supply fresh air, seek medical attention for breathing difficulty.
Skin Contact: Wash affected skin with soap and plenty of water immediately. Remove any contaminated clothing.
Eye Contact: Rinse cautiously with water for several minutes. Lift eyelids to ensure complete removal. Contact an ophthalmologist if irritation does not quickly subside.
Ingestion: Rinse mouth with water, seek medical help. Do not induce vomiting unless directed by a medical professional.
Symptoms of Exposure: Redness, itching, discomfort for skin. Eyes may show tearing and burning. Large doses could cause nausea.
Suitable Extinguishing Media: Dry chemical, CO₂, foam, or water spray. Do not use direct water stream.
Special Hazards: Fumes, toxic phosphorus oxides, sulfur oxides, hydrogen fluoride, and other noxious gases may evolve if exposed to fire.
Protective Equipment for Firefighters: Full protective clothing and self-contained breathing apparatus. No skin exposure should be permitted.
Advice: Contain runoff from fire control or dilution to prevent environmental contamination.
Personal Precautions: Use chemical splash goggles, chemical-resistant gloves, and protective clothing. Remove all ignition sources.
Environmental Precautions: Prevent spills from entering drains, sewers, or waterways. Alert relevant authorities if a large spill threatens the ecosystem.
Cleanup Actions: Absorb any spilled material with inert material (sand, diatomaceous earth). Transfer waste to suitable container for disposal.
Decontamination: Wash the spill site after cleanup is complete, ventilate the area thoroughly.
Safe Handling Practices: Always handle in a chemical fume hood or well-ventilated area, wearing eye and skin protection.
Avoidance Measures: Never breathe vapor or mist. Do not allow contact with water-reactive substances.
Storage Conditions: Remain in tightly closed original containers, store away from direct sunlight and strong oxidizers. Ideal temperature ranges from 2°C to 8°C.
Incompatible Materials: Strong bases, oxidizers, and reducing agents, which might trigger reactions.
Occupational Exposure Limits: No official regulatory limit, but work to minimize exposure.
Engineered Controls: Chemical fume hood, local exhaust ventilation, or other engineering controls to keep airborne levels below recommended exposure.
Personal Protection: Wear chemical splash goggles, butyl rubber gloves, and protective lab coat. Consider a face shield for larger transfer operations.
Hygiene Measures: Wash hands after handling, and before eating or drinking. Remove contaminated clothing and wash before reuse.
Appearance: Colorless to pale yellow liquid, may appear slightly viscous.
Odor: Mild, ether-like odor possible.
Boiling Point: Above 300°C (decomposes before boiling.)
Melting Point: Roughly -30°C
Flash Point: Greater than 110°C
Solubility: Water-soluble (moderate), fully miscible with many polar organic solvents
Vapor Pressure: Very low, limited volatility at room temperature.
Density: About 1.41 g/cm³
pH: Not applicable (non-aqueous liquid)
Viscosity: Higher than water, can vary with temperature.
Decomposition Temperature: Begins to break down at 250°C, releasing hazardous fumes.
Partition Coefficient (Log Pow): Not measured, estimated to be low due to ionic character.
Auto-ignition Temperature: Data not widely reported.
Chemical Stability: Stable at room temperature under recommended storage.
Reactivity: Non-reactive with most common lab materials under ambient conditions.
Conditions to Avoid: High temperatures, strong oxidizers, sources of ignition, direct sunlight.
Incompatible Materials: Strong acids, strong bases, reactive metals.
Hazardous Decomposition Products: Can generate toxic gases on decomposition — phosphorus oxides, sulfur oxides, hydrogen fluoride, and carbon monoxide dangers are real in fire events.
Potential Inhalation Effects: Vapors or mists may irritate respiratory system.
Skin Contact Risks: Prolonged or repeated skin contact may produce irritation, redness, even mild dermatitis.
Eye Contact Risks: Direct splashes likely to cause burning, watering, and redness.
Ingestion Toxicity: Ingesting even small quantities could lead to irritation, nausea, vomiting. Larger doses have not been fully tested in humans.
Chronic Effects: No long-term data for cancer, reproductive, or genetic toxicity.
Acute Exposure Data: Animal studies suggest low oral and dermal toxicity, but lack of widespread testing keeps the risk from being dismissed.
Other Effects: Allergic sensitivity remains possible after long-term or repeated exposure.
Ecotoxicity: Moderately toxic to aquatic organisms. Spills or significant waste should never enter lakes or streams.
Persistence and Degradability: Ionic liquids do not readily biodegrade, so residues may possibly persist in environmental matrices.
Bioaccumulation: Limited evidence points to possible low bioaccumulation.
Mobility in Soil: Moderate mobility in groundwater, mainly dissolves in water and can spread if released.
Other Global Effects: No current data suggests direct threats to mammals or birds in field-level exposures.
Waste Disposal Methods: Collect all waste in sealed, clearly labeled containers. Send to hazardous waste facility certified for chemicals containing fluorine, sulfur, phosphorus.
Contaminated Materials: Dispose of used gloves, contaminated protective clothing, and absorbents as hazardous chemical waste.
Sewage and Drain: Do not flush material or solutions down public sewers or drains.
Special Instructions: Use local, regional, and national hazardous waste disposal rules for all steps. Seek advice of qualified experts.
UN Number: Not assigned (non-ADR, non-DOT regulated for most volumes and concentrations).
Transport Hazard Class: Not classed as dangerous for transport under ECE230, IMDG, or IATA rules.
Packing Group: Not allocated.
Marine Pollutant: Not currently listed as marine pollutant. Prevent release to water bodies regardless, to avoid localized harm.
Special Precautions: Avoid temperature extremes during shipment. Original packaging preferred during all transport.
TSCA: Not listed under the Toxic Substances Control Act.
EINECS/ELINCS: Not registered.
REACH: Not evaluated for use in Europe; may require notification.
OSHA Hazards: Classified as hazardous due to irritation potential.
Other National Inventory: Consult the relevant national inventory for compliance if importing or exporting.
