Other Components: Trace impurities (none classified as hazardous or present over 1%)
Eye Contact: Rinse with gentle stream of water for at least 15 minutes, keep eyelids apart, seek medical advice if irritation persists
Skin Contact: Wash exposed area with plenty of soap and water, remove contaminated clothing and footwear
Ingestion: Rinse mouth with water, do not induce vomiting, seek medical attention immediately if feeling unwell
Inhalation: Move to location with fresh air, keep comfortable, get medical help with any breathing difficulty
Notes to Physician: Treat symptoms conventionally, no known specific antidote exists
Suitable Extinguishing Media: Carbon dioxide, dry chemical powder, or foam; water spray can be used for cooling
Unsuitable Media: High volume water jets may spread product
Special Hazards: Thermal decomposition leads to toxic fumes like nitrogen oxides, bromine compounds
Protective Equipment: Use full protective gear with self-contained breathing apparatus
Fire Fighting Methods: Avoid breathing vapors, keep containers cool by spraying with water if safe, evacuate area if fire spreads
Personal Precautions: Wear gloves, goggles, face shield, impermeable lab coat; prevent skin and eye contact
Environmental Precautions: Prevent spill from entering waterways, soil, or drains
Clean-Up Methods: Scoop up using non-sparking tools, place residue in sealed containers for disposal, ventilate area well
Decontamination: Wash surfaces thoroughly with soap and water after removal
Safe Handling Notes: Minimize dust, avoid splashing, do not eat, drink, or smoke while handling; keep containers tightly closed
Storage Conditions: Store in a cool, dry, well-ventilated place away from strong acids, bases, oxidizers
Packing Materials: Store in original container preferably glass or chemically resistant plastic
Transfer Procedures: Use appropriate tools to avoid spills and minimize contact
Engineering Controls: Use chemical fume hood, eyewash stations, emergency showers
Personal Protective Equipment: Chemical-resistant gloves, safety goggles, laboratory coat, closed-toe footwear
Respiratory Protection: Dust mask or respirator if handling large amounts or powder
Workplace Practices: Remove contaminated clothing, wash hands thoroughly after handling, avoid inhalation and direct skin contact
Exposure Limits: Not established by OSHA, NIOSH, ACGIH
Appearance: White to off-white solid or powder
Odor: Odorless
Melting Point: 70–90°C (variable with purity)
Boiling Point: Decomposes before boiling
Solubility: Moderately soluble in water, highly soluble in alcohols and polar organic solvents
Density: 1.30–1.35 g/cm³ at 25°C
pH (aqueous solution): Approximately neutral (6–8)
Vapor Pressure: Negligible at ambient conditions
Partition Coefficient: No data available
Flash Point: >100°C
Chemical Stability: Stable at ambient conditions, avoid moisture for best shelf life
Incompatibilities: Strong oxidizing agents, strong acids or bases may cause decomposition
Hazardous Decomposition: Nitrogen oxides, bromine fumes, imidazole-based fragments
Polymerization: Not known to occur
Conditions to Avoid: High heat, prolonged ultraviolet exposure, mechanical shock
Acute Toxicity: Oral and dermal toxicity data are limited, but not considered highly toxic by standard routes
Chronic Effects: No comprehensive long-term studies, but not recognized as a carcinogen or mutagen
Irritation: May cause redness, slight burns, or discomfort on eyes, skin, or mucous membranes
Sensitization: Skin or respiratory sensitization unlikely, but not excluded
Other Effects: Inhalation of dust or aerosols may bring cough, sore throat, or respiratory symptoms
LD50 Values: Data not freely available, low acute toxicity expected based on similar imidazolium salts
Aquatic Toxicity: Moderate toxicity to aquatic life, chronic exposure may alter local aquatic ecosystems
Persistence and Degradability: Slowly biodegradable, persistent in soil and water if released
Bioaccumulation: Very low potential, thanks to ionic structure
Mobility in Soil: Moves readily in moist soil, but binds to organic matter
Other Environmental Hazards: Avoid large scale disposal to drains or open waters, since small organisms are more vulnerable
Waste Disposal: Send solids and contaminated absorbents to certified chemical waste processors
Container Disposal: Empty containers may be hazardous, rinse and dispose per local requirements
Sewage Disposal: Do not flush into drains or sewers
Recycling: Reuse or recycle if possible through professional channels
