Protective Equipment: Chemical resistant gloves, goggles, laboratory coat or chemical apron, suitable respiratory protection if dust or vapors present
Environmental Precautions: Prevent release to waterways and drains, contain as much of the material as possible, use barriers to prevent spread
Cleanup Methods: Absorb spill with inert material such as dry sand or vermiculite; scoop up residue into sealable containers; wash area with detergent and water
Waste Disposal: Place collected waste in properly labeled containers for disposal according to local environmental regulations
Decontamination: Clean tools and equipment used for spill response before further use; handle all cleaning materials as potentially hazardous waste
Precautions for Safe Handling: Use contained systems or keep containers closed when not in use, minimize physical disturbances, utilize chemical fume hoods or local exhaust
Hygiene Measures: Wash hands thoroughly after handling; prohibit food, drink, or smoking in chemical work spaces
Storage Conditions: Store in a cool, dry, well-ventilated area with minimal temperature variation; containers should be tightly sealed and appropriately labeled
Compatible Materials: Keep away from strong oxidizers and acids; avoid materials prone to attack from fluorinated compounds
Incompatible Conditions: Exposure to heat, moisture, light, or extreme pH can compromise chemical stability
Packaging Requirements: Only use containers made from chemical-resistant polymers or glass; double containment advisable for large quantities or long-term storage
Occupational Exposure Limits: No formal exposure limits set by OSHA, NIOSH or ACGIH; internal controls recommended; treat as particulate chemical dust
Engineering Controls: Implement chemical fume hoods or dedicated extraction systems to contain vapors and dusts; ensure regular air monitoring
Personal Protective Equipment: Nitrile or neoprene gloves, splash-proof safety goggles or face shield, laboratory coat or apron
Respiratory Protection: Wear NIOSH-approved particulate respirators or air-purifying cartridges in situations where dust/vapor may exceed recommended levels
Environmental Controls: Prevent discharge to environment, use chemical containment and spill trays; monitor effluent streams for contaminants
Other Control Measures: Emergency showers and eye wash stations should be available and operational in areas of use
Appearance: White to off-white crystalline solid or powder (color may vary slightly with impurity level)
Odor: Essentially odorless
Melting Point: Approximately 40–60°C (varies by hydration and crystal form)
Boiling Point: Not determined (decomposes before reaching boiling point)
Density: 1.11–1.15 g/cm³ at 20°C (estimate)
Solubility: Moderately soluble in organic solvents such as acetonitrile, dichloromethane, toluene; limited aqueous solubility
Vapor Pressure: Negligible under ambient conditions
pH: Not measured directly in water; solutions may be slightly acidic due to trace imide hydrolysis
Partition Coefficient (Octanol/Water): Not measured directly; expected to partition strongly into organic phases
Flash Point: >180°C (closed cup, estimate; always confirm with supplier batch data)
Other Data: Stable under standard laboratory temperatures; material becomes sticky at or above melting point
Chemical Stability: Stable at ambient temperatures under dry, sealed conditions; reacts upon prolonged exposure to heat, acids, or moisture
Incompatible Materials: Strong acids, strong bases, oxidizing agents, reactive metals
Hazardous Decomposition: Heating or burning produces fluorinated gases, sulfur oxides, nitrogen oxides, and possibly imide-derived volatiles
Conditions to Avoid: Humidity, exposure to strong light, high temperature, mechanical shock
Polymerization: No reports of hazardous polymerization under normal handling
Special Reaction Risks: Mixing with certain laboratory chemicals may form hazardous by-products; always consult a compatible materials chart before new procedures
Routes of Exposure: Inhalation, skin and eye contact, incidental ingestion possible during laboratory handling
Acute Toxicity: No mammalian LD50 data catalogued; analogs suggest low acute toxicity by oral and dermal exposure, but absence of comprehensive long-term studies warrants precaution
Irritation: Skin and eye contact may cause redness, irritation or itching; repeated or prolonged exposure may worsen effects
Sensitization: No sensitization data available; use barrier precautions to prevent all unnecessary exposure
Chronic Effects: No human studies on long-term exposure; precautionary use and avoidance of skin or respiratory exposure remain prudent
Carcinogenicity: Neither IARC, NTP, nor OSHA list this compound as a confirmed or suspected carcinogen
Mutagenicity/Teratogenicity: No definitive data available; structurally related compounds rarely demonstrate such risks in short-term studies
Aquatic Toxicity: Environmental fate unpredictable due to fluorinated structure and imide anion stability; aquatic toxicity not fully characterized, but persistence and potential bioaccumulation are flagged concerns
Persistence and Degradability: Imide and fluorinated moiety confer environmental resistance to typical biodegradation pathways; chemical resists breakdown in water and soil
Bioaccumulation: Not directly studied for this cation-anion pair, but structurally similar compounds accumulate in organisms, especially aquatic life
Mobility in Soil: Tends to partition to organic matter, limited direct mobility in mineral soil fraction; migration possible if dissolved in organic solvent spills
Other Adverse Effects: Combustion products pose longer-term ecological risks; avoid uncontrolled releases or incineration in open settings
Waste Generation: Classify all process waste as chemical waste; prevent cross-contamination with nonhazardous debris
Disposal Method: Dispose of through authorized hazardous waste incineration or licensed chemical landfill sites able to handle persistent fluorinated materials; never pour into drains or regular trash
Container Disposal: Triple rinse empty containers with suitable solvent, collect rinse residues for disposal with hazardous chemical waste
Legal Considerations: Comply with all local, state, and federal waste handling statutes; document disposal for compliance audits
Decontamination: All cleanup equipment and surfaces require thorough washing; all washings must be managed as hazardous waste
