Chemical Name: 1-Ethyl-3-Methylimidazolium Iodide
Common Name: EMIM I
Concentration: 98–100%
Impurities: Traces of related imidazolium compounds, water <1%, iodide sources as stabilizers or synthesis residues
Identifiers: No additive substances expected for pure laboratory grade material
Inhalation: Move person to fresh air, keep comfortable, seek medical attention if symptoms continue—such as coughing, dizziness, breathing difficulty
Skin Contact: Remove contaminated clothing, wash thoroughly with water, use soap if available, seek help for irritation
Eye Contact: Rinse cautiously with water for at least 15 minutes, remove contact lenses if present and easy to do, seek medical advice promptly
Ingestion: Rinse mouth with water, give small amounts of water to drink if person is conscious, never give anything by mouth to an unconscious individual, call a doctor or poison center
Suitable Extinguishing Media: Use foam, dry chemical, or CO₂. Water spray can be used for larger fires.
Specific Hazards: May emit toxic iodine vapors and nitrogen oxides under fire conditions.
Protective Equipment: Wear full protective clothing including self-contained breathing apparatus.
Fire-fighting Procedures: Approach fire from upwind, keep containers cool with water spray, avoid inhaling combustion products, contain run-off to prevent entry into water systems
Personal Precautions: Use protective gloves, safety goggles, chemical-resistant clothing. Avoid breathing dust or vapor.
Environmental Precautions: Prevent release into drains, water courses, soil.
Cleanup Methods: Absorb with vermiculite, sand, or inert material. Collect in sealed containers for disposal. Use non-sparking tools. Ventilate area and wash contaminated surfaces.
Handling Precautions: Handle under a fume hood, avoid skin and eye contact, prevent dust or aerosol formation.
Storage Recommendations: Store at room temperature in a well-ventilated, dry area, away from strong oxidizers and incompatible substances. Keep container tightly closed, protect from light to avoid iodine degradation and hazard increase.
Incompatibilities: Strong bases, strong oxidizing agents, especially nitrate and peroxide compounds
Engineering Controls: Use fume hoods, local exhaust ventilation.
Respiratory Protection: Use NIOSH-approved respirator if aerosol or dust forms.
Skin Protection: Lab coat, impervious gloves (nitrile or neoprene best).
Eye Protection: Chemical safety goggles.
Hygiene Measures: Wash hands before breaks and after handling, remove contaminated clothing, clean surfaces frequently to reduce cross-contamination.
Appearance: Pale yellow to brownish solid or viscous liquid
Odor: Slightly sweet or iodide smell
Molecular Weight: 254.07 g/mol
Melting Point: 80–90°C (can be lower in moist conditions)
Boiling Point: Decomposes above 200°C
Solubility: Soluble in water, acetonitrile, ethanol
pH: Weakly acidic when dissolved in water
Vapor Pressure: Negligible at room temperature
Flash Point: Data generally not available, estimated >100°C
Chemical Stability: Stable under recommended storage conditions
Possibility of Hazardous Reactions: Reacts with strong oxidizers, may release iodine vapors
Conditions to Avoid: Exposure to light and heat, contact with incompatible chemicals
Incompatible Materials: Strong oxidants, strong bases
Hazardous Decomposition Products: Iodine, nitrogen oxides, imidazole ring breakdown products
Acute Toxicity: Swallowing produces moderate toxicity; estimated LD50 (oral, rat) between 300–2000 mg/kg
Skin Irritation: Causes redness, dryness, possibly dermatitis
Eye Irritation: Causes moderate to severe irritation, redness, pain
Sensitization: No reliable evidence of sensitization in repeated exposures
Chronic Effects: Data insufficient, but iodide exposure in general may impact thyroid, prolonged skin contact could dry or crack skin, less information available for chronic ingestion
Target Organs: Eyes, skin, thyroid gland (due to iodide content)
Carcinogenicity/Mutagenicity: No data indicating carcinogenicity or mutagenicity
Ecotoxicity: Iodide ions can be toxic to aquatic life at high concentrations, persistence in the environment
Mobility in Soil: Due to water solubility, potential to move in ground and surface water
Bioaccumulation Potential: Not expected to concentrate significantly in biological tissues
Degradability: Not readily biodegradable, may persist unless chemically broken down
Other Effects: Significant spills could disrupt aquatic environments or soil microorganism populations
Product Disposal: Treat as hazardous waste. Incinerate in permitted facility, or dispose through licensed chemical waste contractor.
Contaminated Packaging: Rinse container, dispose of containers as hazardous waste, never reuse for food or drink
Environmental Instructions: Never dispose of in the environment, storm drains, or uncontrolled waste, always follow local, regional, and national regulations for chemical disposal
UN Number: Not assigned for small quantities or most research uses
Proper Shipping Name: 1-Ethyl-3-Methylimidazolium Iodide or Ionic Liquid
Hazard Class: Not regulated in most jurisdictions for low danger, but confirm with shipment and country-specific regulations
Packing Group: Usually not assigned, but packaging should prevent leaks
Marine Pollutant: Not officially classified, but avoid release to water
Special Precautions: Label package clearly, include emergency contact details, ship in sealed, robust containers to prevent accidental release
