Chemical Name: 1-Butyl-2,3-dimethylimidazolium iodide
CAS Number: 144089-73-4
Purity: More than 95% (varies with supplier)
Impurities: May contain trace organic or inorganic salts or free imidazole depending on synthesis route
Eye Contact: Flush with running water for at least 15 minutes, remove contact lenses if possible, seek medical attention for persistent irritation.
Skin Contact: Immediately wash exposed skin with soap and water, remove contaminated clothing, rinse skin for several minutes.
Inhalation: Move affected individual to fresh air, administer oxygen if breathing difficulty develops, seek medical assistance for coughing or difficulty breathing.
Ingestion: Rinse mouth with water, do not induce vomiting, call poison control or seek emergency medical help if large amount swallowed or symptoms develop.
Suitable Extinguishing Media: Use water spray, foam, dry chemical or carbon dioxide extinguishers.
Hazardous Combustion Products: Emits toxic fumes of carbon oxides, nitrogen oxides, irritable iodine vapors if heated or burned.
Precautions for Firefighters: Wear self-contained breathing apparatus and protective clothing to prevent contact with skin and eyes.
Special Risks: Containers may rupture due to buildup of pressure if heated; stay upwind of fire, douse contaminated surfaces thoroughly to avoid lingering hazard.
Personal Protection: Use proper gloves, eye protection, and lab coats; avoid direct contact with spilled substance.
Containment Method: Scoop up solid or neutralize liquid with inert absorbent material like sand or vermiculite, avoid mixing with incompatible substances.
Cleanup: Sweep up and collect in clearly labeled waste container, wipe affected area with damp cloth, ventilate spill area if indoors.
Environmental Care: Prevent release into sewers, soil, streams, or groundwater, inform relevant authorities if large quantities enter environment.
Handling Tips: Use in a well-ventilated area with local exhaust, avoid breathing dust or vapor, keep container tightly closed after use.
Hygiene Measures: Wash hands after handling, remove contaminated clothing, keep food and drink away from work area.
Storage Conditions: Store in cool, dry area, away from heat sources and direct sunlight, avoid humidity exposure as some ionic liquids absorb water quickly.
Incompatibilities: Avoid strong oxidizers, acids, alkaline materials, and moisture.
Engineering Controls: Use fume hood and/or adequate exhaust to limit exposure, employ closed systems if possible in industrial application.
Respiratory Protection: If risk of inhalation exists, wear suitable, approved respirator; lower-risk handling usually manageable without provided dust does not become airborne.
Skin Protection: Nitrile or neoprene gloves recommended, laboratory coat and long sleeves reduce possible skin exposure.
Eye Protection: Safety goggles or face shield necessary during filling, pouring, or cleaning.
Environmental Controls: Monitor air and wastewater where regular, large-scale handling takes place.
Appearance: Crystalline solid or viscous liquid, colorless to pale yellow, sometimes pale brown
Odor: Odorless or faint organic scent
Odor Threshold: Not established
Melting Point: Around 90°C
Boiling Point: Decomposes before boiling
Flash Point: Approx. 225°C
Solubility: Soluble in water, polar organics (DMSO, methanol, acetonitrile)
Vapor Pressure: Not expected to vaporize significantly at ambient temperature
Density: About 1.6 g/cm³
Other Data: Hygroscopic, forms stable solutions with alcohols and some hydrocarbons
Chemical Stability: Stable under recommended storage and handling conditions, prone to slow degradation with moisture or strong acids.
Reactivity: May react with strong oxidizing agents, some metals under certain conditions due to iodide ion.
Hazardous Decomposition Products: Iodine vapor, nitrogen oxides, carbon monoxide/dioxide on overheating or combustion.
Polymerization: No hazardous polymerization expected.
Other Risks: Can discolor over time; decomposition creates increasingly hazardous byproducts upon contact with incompatible materials.
Routes of Exposure: Skin, eyes, inhalation, ingestion
Acute Effects: Irritation to skin and eyes, coughing, mild respiratory distress
Chronic Effects: Limited data, but regular exposure should be minimized due to possible cumulative irritation
Toxicity Data: LD50 (oral, rat) > 2,000 mg/kg (expected, based on similar compounds)
Carcinogenicity: No data available showing carcinogenic properties
Mutagenicity: Insufficient data, though structure similar to non-mutagenic ionic liquids
Sensitization: Sensitizing potential not fully studied. Handle cautiously as a precaution.
Ecotoxicity: Data limited; other imidazolium salts show moderate aquatic toxicity, can affect fish and invertebrates at high concentrations.
Persistence and Degradability: Stable in typical environmental settings; not quickly biodegradable, may accumulate in soil or water.
Bioaccumulation: Low potential expected based on structure, but caution warranted as iodide ions may accumulate in some plants or marine organisms.
Mobility in Soil: Ionic nature may enhance leaching in wet soils, especially around accidental spills.
Other Effects: Avoid disposal in waterways to limit impact on aquatic life and ecosystem balance.
Waste Disposal Methods: Collect liquid or solid waste in clearly labeled, chemically compatible containers; hand over to licensed waste disposal contractor for incineration or processing.
Container Handling: Rinse containers with copious water and solvent, then crush, puncture, or otherwise prevent reuse by unauthorized handlers.
Environmental Notes: Never pour down drains, directly onto land, or send in regular trash; follow local environmental guidelines strictly.
Special Precautions: Consult local and national authorities for permitted methods and restrictions on disposal.
UN Number: Not assigned due to low acute hazard, but consult with logistics provider for packaging requirements.
Transport Hazard Class: Not classified as dangerous for transport according to current regulations.
Packing Group: Not applicable
Special Transport Precautions: Use sealed containers, keep upright, shield from heat and sunlight, avoid transport with incompatible materials.
Labels: Standard chemical marking and hazard identification recommended.
U.S. Regulations: Not listed as a hazardous substance under TSCA, CERCLA, SARA, but subject to chemical inventory and reporting.
EU Regulations: No specific REACH restriction for this substance; typical chemical control laws apply.
Other Jurisdictions: Observe country-specific requirements for handling, labeling, research, or disposal.
Occupational Limits: No established exposure limits under OSHA, ACGIH, or DFG.
Lab Use: Use good laboratory practice and report spillage or exposure per institutional guidelines.
