General Advice: Obtain medical attention if symptoms appear or persist
Inhalation: Remove victim to fresh air; ensure clear airways; provide artificial respiration if necessary; consult a physician immediately for persistent difficulties
Skin contact: Remove contaminated clothing; rinse skin with plenty of water for at least 15 minutes; seek medical advice if irritation continues
Eye contact: Flush eyes gently under running water for at least 15 minutes; remove contact lenses if quick and easy; get medical help
Ingestion: Rinse mouth; avoid vomiting unless directed; seek emergency medical attention
Symptoms and effects: May cause redness, irritation; repeated exposure brings intensifying risk
Medical attention: Symptomatic treatment; no specific antidote known
Suitable extinguishing media: Dry chemical, carbon dioxide, alcohol-resistant foam, water spray (never a direct jet)
Specific hazards: Emits bromide-containing vapors, carbon oxides, nitrogen oxides upon combustion
Firefighting instructions: Firefighters use self-contained breathing apparatus and protective clothing
Explosion hazard: More likely to smolder than to explode, but dust or fine droplets can heighten burn risk
Protective measures: Properly ventilate area, prevent chemical runoff into drains
Personal precautions: Avoid eye or skin contact; put on appropriate gloves, goggles, protective clothing; ventilate area immediately
Spill containment: Stop further leakage or spillage if it's safe; keep away from drains, soil, or waterways
Method for cleanup: Sweep up or absorb with inert absorbent (sand, vermiculite); place in suitable container for disposal; clean spill location with water and mild detergent
Environmental precautions: Prevent from entering water bodies or sewers; notify authorities as required
Emergency procedures: Isolate area; restrict access until cleanup complete
Handling precautions: Handle in a chemical fume hood; wear gloves and eye protection; avoid inhalation or prolonged exposure
Safe handling advice: Wash hands thoroughly after handling; handle with tools or dedicated scoops; keep container tightly sealed
Storage conditions: Store at room temperature in a tightly closed, clearly labeled container; avoid heat, flame, moisture
Incompatible materials: Strong oxidizers, acids, reducing agents
Special packaging: Use corrosion-resistant packaging materials
Exposure limits: No occupational exposure limits established for this compound
Engineering controls: Use local exhaust ventilation or work in a fume hood
Personal protective equipment: Chemical-resistant gloves, safety goggles or glasses with side shields, lab coats, suitable respiratory protection if dust or vapors form
Hygiene measures: Remove contaminated clothing; wash hands with soap before eating, drinking, or leaving lab
Control parameters: Monitor workspaces for airborne concentrations if available
Appearance: White to off-white crystalline solid
Odor: Odorless or faint chemical scent
Molecular Weight: 251.12 g/mol
Melting Point: 80–90°C
Boiling Point: Decomposes before boiling
Vapor Pressure: Not measurable at room temperature
Solubility: Highly soluble in water, alcohol, and polar aprotic solvents
Density: Approximately 1.3 g/cm³
pH: Slightly acidic to neutral in water
Stability in air: Stable under recommended storage conditions
Chemical stability: Stable under ambient temperatures, dry air, and normal pressures
Hazardous reactions: Can react vigorously with strong oxidizing or reducing agents, acids
Decomposition products: Heating releases hydrogen bromide, nitrous gases, carbon monoxide, carbon dioxide
Incompatibility: Avoid mixing with oxidizers, mineral acids, strong bases
Reactivity warnings: Avoid exposing to open flames, excessive heat, or moisture
Acute toxicity: Limited toxicity data available, but similar ionic liquids show moderate oral and dermal toxicity
Potential effects: Skin and eye irritation; inhalation can trigger coughing, mild respiratory symptoms
Chronic effects: Prolonged or repeated skin contact may cause dermatitis; data on carcinogenicity or reproductive effects not documented
Routes of exposure: Inhalation, ingestion, skin, and eye contact
Target organs: Eyes, skin, respiratory tract
Other effects: May cause gastrointestinal discomfort if swallowed
Ecotoxicity: Poorly studied, but like many quaternary ammonium salts and ionic liquids, outcomes may include moderate fish and daphnia toxicity; avoid environmental release
Persistence and degradability: Expected to be persistent in soil and water; low biodegradability
Bioaccumulation: Low potential for bioaccumulation based on physicochemical properties
Mobility in soil: Mobile in water-rich environments, high solubility increases risk for aquatic spread
Other adverse effects: No known ozone depletion, but unintended broad aquatic discharge raises concerns
Waste disposal methods: Dispose of as hazardous laboratory waste per local, regional, national, and international regulations; incinerate at an approved facility
Container disposal: Triple-rinse empty containers and send for recycling or disposal with chemical waste
Precautions: Do not dispose of in household waste; do not flush to sewer
Contaminated packaging: Treat as hazardous; label and segregate from other waste streams
