Skin Contact: Wash with mild soap and plenty of water for at least 15 minutes. Remove contaminated clothing.
Eye Contact: Rinse slowly with water for several minutes, lifting eyelids. Continue for at least 15 minutes. Get medical help if irritation stays.
Ingestion: Rinse out mouth. Do not force vomiting. Drink small amounts of water if not unconscious. Call poison center or physician.
Note to Physicians: Treat symptoms, keep patient under observation for potential delayed effects.
Suitable Extinguishing Media: Dry chemical, carbon dioxide, foam
Unsuitable Media: Direct water jet may spread material
Specific Hazards: May give off toxic fumes (nitrogen oxides, chlorine, carbon oxides) on burning
Protective Equipment: Wear self-contained breathing apparatus and full protective clothing
Fire-Fighting Instructions: Avoid downwind exposure; prevent runoff into drains and watercourses
Personal Precautions: Use gloves, protective goggles, and lab coats; ensure good ventilation
Spill Response: Absorb with inert material (sand, earth); collect by scoop or vacuum
Cleanup Procedures: Place material in sealed, labeled containers for disposal
Environmental Precautions: Prevent release into drains, waterways, and soil
Decontamination: Wash spill site with mild detergent and copious water after cleanup
Handling: Avoid inhalation, skin, or eye contact. Wear appropriate PPE at all times. Only trained personnel should handle.
Storage: Keep container tightly closed in a dry, cool, and well-ventilated place. Store away from strong oxidizers and moisture. Label all containers with chemical and hazard identities.
Incompatibilities: Avoid contact with oxidizing agents, acids, or bases
Bulk Storage Advice: Use corrosion-resistant containers, protect from direct sunlight
Engineering Controls: Use within chemical fume hoods or localized exhaust ventilation
Eye Protection: Chemical safety goggles and face shield if significant splashing risk
Skin Protection: Nitrile or butyl rubber gloves, long-sleeved lab coats
Respiratory Protection: Use certified respirators if airborne dust/vapor levels approach recommended limits
Workplace Monitoring: Regular surface wipe tests for contamination, air monitoring where evaporation may occur
Hygiene: Wash hands before breaks, at end of shift, and after handling
Appearance: White to pale yellow solid or crystalline powder
Odor: Mild, characteristic
Melting Point: Approx. 120–130°C
Boiling Point: Decomposes before boiling
Density: ~1.15 g/cm³ at 25°C
Solubility: Highly soluble in water, soluble in polar organic solvents
pH: 5–8 (aqueous solution)
Vapor Pressure: Negligible at room temperature
Flash Point: Not readily flammable
Partition Coefficient (log Kow): Not available; low bioaccumulation potential expected
Chemical Stability: Stable under recommended storage and handling conditions
Hazardous Reactions: May react with strong oxidizing materials, intense acids, and bases
Decomposition Products: Nitrogen oxides, carbon oxides, hydrogen chloride gases
Polymerization: Not expected under normal laboratory conditions
Condition to Avoid: Excessive heat, moisture, incompatible reactive substances
Acute Oral Toxicity: Data limited, similar imidazolium salts LD50 (oral, rat): 300–1000 mg/kg
Skin Irritation: Can cause redness and irritation with prolonged or repeated contact
Eye Irritation: May provoke irritation, tearing, or redness
Inhalation: Inhalation of dust or fumes may irritate respiratory tract, coughing possible
Chronic Effects: Little long-term data; structurally similar compounds have shown low mutagenicity; always err on side of caution
Other Risks: Pre-existing skin or respiratory disorders can worsen with exposure
Aquatic Toxicity: Limited research, persistent ionic liquids can have moderate toxicity to aquatic invertebrates
Persistence and Degradability: Slow degradation, not easily biodegradable
Bioaccumulation: Expected to have low potential due to high water solubility and moderate molecular weight
Mobility in Soil: High mobility likely due to ionic nature
Other Adverse Effects: Avoid release to the environment, as long-term aquatic effects cannot be excluded
Waste Disposal: Treat as hazardous chemical waste; consult regulation before disposal
Recommended Method: Incineration under controlled conditions at licensed chemical waste facility
Container Disposal: Triple-rinse and puncture empty containers prior to landfill or recycling, as permitted
Precautions: Do not discharge into surface water, municipal sewage, or natural soil
Regulatory Controls: Local, regional, and national regulations take precedence; consult waste management agencies
UN Number: Not assigned for this compound specifically
