Purity: >99%
Impurities: None known at significant concentrations, trace solvents from synthesis unavoidable in small scale labs
Inhalation: Move to fresh air. If symptoms develop, seek immediate medical attention. Provide oxygen if breathing difficulty occurs.
Skin Contact: Remove contaminated clothing. Wash skin with flowing water and mild soap for several minutes. If irritation occurs, consult a doctor.
Eye Contact: Rinse eyes gently under running water for at least 15 minutes. Lift eyelids. Remove contact lenses if present. Seek medical help if discomfort persists.
Ingestion: Rinse mouth with water. Never give anything by mouth to an unconscious person. Contact poison control or a physician right away.
Suitable Extinguishing Media: Carbon dioxide, dry chemical powder, alcohol resistant foam. Avoid high pressure water stream directly on the burning liquid.
Specific Hazards: Releases toxic and irritating vapors under fire conditions, such as carbon oxides, sulfur oxides, nitrogen oxides, hydrogen fluoride.
Special Protective Equipment for Firefighters: Wear self-contained breathing apparatus and full firefighting protective gear.
Firefighting Instructions: Contain run-off water to prevent entry into sewers/drains. Cool containers with water spray to prevent bursting from pressure buildup.
Personal Precautions: Wear protective gloves, eye and face protection, and lab coat. Ensure good ventilation. Avoid inhalation and skin/eye contact.
Environmental Precautions: Prevent entry into waterways and soil to avoid contamination. Alert proper authorities in case of large spills.
Clean-Up Methods: Absorb with inert material (sand, vermiculite), collect with non-sparking tools, and place in chemical waste container. Wash spill area with abundant water.
Handling: Use only in well-ventilated areas or fume hood. Avoid contact with mucous membranes, skin, and eyes. No eating or drinking near use area.
Storage: Keep container tightly closed in a cool, dry, well-ventilated space, away from incompatible substances such as strong acids, oxidizers. Protect from direct sunlight and moisture.
Special Storage Conditions: Store in original containers, clearly labeled, preferably in secondary containment in chemical stores.
Engineering Controls: Work with fume hood or local exhaust recommended for liquid transfer and processing.
Personal Protective Equipment: Lab gloves (nitrile or neoprene), safety goggles or face shield, laboratory coat, appropriate footwear.
Respiratory Protection: If ventilation is inadequate, use NIOSH approved respirator for organic vapors and particulates.
Hygiene Measures: Wash hands thoroughly after handling, remove contaminated clothing and wash before reuse.
Appearance: Colorless to pale yellow liquid
Odor: Slight, characteristic
Melting Point/Freezing Point: -5 to 10 °C
Boiling Point: Decomposes above 250 °C
Flash Point: >130 °C (closed cup, approximate)
Solubility: Water miscible, soluble in common organic solvents
Vapor Pressure: Negligible at room temperature
Density: 1.35–1.40 g/cm3 at 20 °C
Viscosity: Relatively high viscosity, typical for ionic liquids
pH: Not measurable (substance used as solvent or neat)
Chemical Stability: Stable at room temperature in sealed containers.
Reactivity: Largely inert to air under ambient laboratory conditions.
Conditions to Avoid: Heat, open flames, exposure to strong acids, oxidizers or bases.
Hazardous Decomposition Products: Fumes of CO2, CO, NOx, SOx, HF, imidazole derivatives at high temperatures.
Routes of Exposure: Skin/eye contact, inhalation, ingestion
Acute Effects: May cause irritation to skin, eyes, respiratory tract; moderately toxic if swallowed
Chronic Effects: Long-term exposure may result in liver or kidney stress, no comprehensive chronic toxicity data for humans
Sensitization: No data indicating skin sensitization
Carcinogenicity: Not classified by IARC, NTP, or OSHA as carcinogenic
Mutagenicity/Teratogenicity: Insufficient data
LD50 (Oral, rat): 300–2000 mg/kg (estimated, based on ionic liquid class analogs)
Target Organs: Eyes, skin, mucous membranes
Ecotoxicity: Toxic to aquatic invertebrates and microalgae at low concentrations. Slow degradation leads to persistent residues.
Persistence and Degradability: Not rapidly biodegradable, persistence likely in soil and water systems
Bioaccumulative Potential: Potential for accumulation in aquatic organisms cannot be excluded
Mobility in Soil: Likely to have some mobility due to solubility in water, major concern for run-off
Other Adverse Effects: Avoid release to the environment due to poor degradability.
Aquatic Toxicity (Daphnia): EC50 < 5 mg/L (calculated)
Waste Treatment: Treat as hazardous chemical waste, avoid direct release to sewage or surface water.
Disposal Methods: Incineration in a chemical waste incinerator with afterburner and scrubber. Consult local and national regulations for options.
Packaging Disposal: Empty containers should be rinsed, collected, and handled as hazardous waste. Do not reuse packaging.
UN Number: Considered for UN 3082 (Environmentally hazardous substance, liquid, N.O.S.)
Transport Hazard Class: 9 (miscellaneous hazardous substances and articles)
Packing Group: III (substances presenting minor danger)
Proper Shipping Name: Environmentally hazardous substance, liquid, n.o.s. (contains ionic liquid)
Marine Pollutant: Yes
Special Precautions: Clearly label cargo, avoid spillage, transport in tightly closed containers, follow regional rules on eco-toxic substances
OSHA: Hazardous chemical under OSHA Hazard Communication Standard
TSCA: Not listed, research use or limited supply only
REACH: Not preregistered or listed as of current database, laboratory quantities permitted
Other International Regulations: Product use, handling, and disposal subject to relevant national environmental protection and chemical safety guidelines
