General Measures: Move person to fresh air and keep comfortable; Seek immediate medical attention as required
Inhalation: Remove to fresh air; If breathing difficulty develops, call for medical help and administer oxygen if available
Skin Contact: Remove contaminated clothing; Rinse skin under running water for several minutes; Seek medical help if irritation persists
Eye Contact: Rinse cautiously with water for at least 15 minutes; Remove contact lenses if present; Get medical advice immediately
Ingestion: Do not induce vomiting; Rinse mouth with water; Call poison control center or physician promptly
Most Important Symptoms: Skin and eye irritation, nausea, respiratory discomfort, headache, gastrointestinal distress, potential systemic toxicity
Suitable Extinguishing Media: Use water spray, alcohol-resistant foam, carbon dioxide, or dry chemical powder
Unsuitable Media: High-pressure water jets as they can spread material
Hazardous Combustion Products: Can emit noxious fumes such as nitrogen oxides, hydrogen cyanide, and carbon monoxide
Firefighter Precautions: Wear full protective gear including self-contained breathing apparatus
Special Hazards: Elevated temperatures may produce toxic vapors; Sealed containers can rupture during fire
Personal Precautions: Evacuate unnecessary personnel; Wear gloves, goggles, and a lab coat; Adequate ventilation is important
Environmental Precautions: Prevent entry into waterways, drains, soil
Methods for Containment: Absorb with inert material (sand, vermiculite); Sweep up and place in a properly labeled disposal container
Cleaning Methods: Wash area with soap and water after initial clean-up; Dispose materials per local regulations
Reference to Other Sections: See Section on Exposure Controls and Disposal Considerations
Handling: Use in well-ventilated spaces; Avoid inhalation and contact with skin or eyes; Keep containers tightly sealed; Wash hands after use
Storage: Store at room temperature, in a dry, cool, well-ventilated area; Keep container tightly closed; Store away from oxidizing agents, strong acids, and moisture
Special Sensitivities: Prevent electrostatic discharge and avoid contamination to preserve material purity
Control Parameters: No specific occupational exposure limits established
Engineering Controls: Use fume hood or adequate exhaust ventilation; Emergency eyewash stations and safety showers available near areas of use
Personal Protective Equipment (PPE): Chemical-resistant gloves (nitrile or similar), safety goggles, lab coat, suitable footwear
Hygiene Measures: Do not eat, drink, or smoke in areas where material is handled; Wash thoroughly with soap and water before breaks or after exposure
Respiratory Protection: If ventilation is inadequate, use a certified respirator with appropriate filters
Appearance: Colorless to pale yellow liquid or solid (room temperature dependent)
Odor: Mild, characteristic
Melting Point/Freezing Point: Ranges from 15°C to 20°C
Boiling Point: Decomposes before boiling at atmospheric pressure
Density: 1.09–1.10 g/cm³
Solubility: Soluble in water, ethanol, acetone
pH: Slightly basic (in aqueous solution)
Partition Coefficient: Not readily available
Vapor Pressure: Practically negligible at normal laboratory conditions
Viscosity: Moderate viscosity, varies with temperature
Flash Point: Approximately 180°C (closed cup)
Auto-ignition Temperature: Data not fully established
Decomposition Temperature: Begins decomposing above 200°C
Chemical Stability: Stable under recommended storage conditions; Avoid strong oxidizers and acids
Reactivity: Not highly reactive, though can hydrolyze with extended moisture exposure
Possibility of Hazardous Reactions: Strong acids may liberate toxic fumes; High temperatures or combustion produces nitrogen oxides, cyanide compounds
Incompatible Materials: Strong acids, strong oxidizers, materials that release strong acids on contact
Hazardous Decomposition Products: Hydrogen cyanide, nitrogen oxides, carbon monoxide, imidazole derivatives
Acute Toxicity: Oral LD50 in rodents reported around 300–600 mg/kg; lower doses may cause gastrointestinal symptoms in humans
Skin Corrosion/Irritation: Causes mild to moderate skin irritation
Serious Eye Damage/Eye Irritation: May lead to eye pain, redness, intense tearing
Respiratory Sensitization: Not a known sensitizer, but inhalation of mist or aerosol should be avoided as it can irritate mucous membranes
Chronic Toxicity: No long-term studies in humans; potential impacts suspected to include mild liver and kidney effects with repeated, high-concentration exposure
Carcinogenicity: Not listed as carcinogen by IARC, NTP, or OSHA
Mutagenicity: No data indicating mutagenic risk currently published
Reproductive Toxicity: No direct evidence for reproductive toxicity, but general caution applies with all ionic liquids
Ecotoxicity: Moderately toxic to aquatic organisms; Dicyanamide anion can disrupt aquatic enzyme systems
Persistence and Degradability: Not readily biodegradable; may persist in wastewater and soil environments
Bioaccumulative Potential: Moderate; ionic nature limits rapid spread, possible accumulation in sediment
Mobility in Soil: Moves slowly through soils due to polarity but can slowly leach
Other Adverse Effects: Large-volume spills can harm aquatic microflora and fauna; Avoid uncontrolled release
Waste Treatment Methods: Incinerate in a chemical incinerator equipped with afterburner and scrubber; Do not pour down drains or allow to reach natural waterways
Contaminated Packaging: Rinse thoroughly and dispose of in accordance with local regulations
Special Precautions: Follow regional, national, and local environmental agency guidance; Certified chemical waste collection strongly recommended
