Skin Contact: Wash area with gentle soap and water, remove contaminated clothing, seek medical care for prolonged irritation
Ingestion: Do not induce vomiting; rinse mouth thoroughly and drink water to dilute; seek urgent medical advice
Acute & Delayed Symptoms: Irritation, redness, headache or dizziness with excessive exposure; note any allergic reactions
Medical Attention and Special Treatment: Symptomatic treatment, monitor for signs of respiratory distress or allergic reaction
Suitable Extinguishing Media: Water spray, dry chemical, carbon dioxide, or alcohol-resistant foam
Unsuitable Media: Avoid direct water jet if not appropriate for surrounding fire
Specific Hazards: Product decomposition may release toxic vapors such as nitrogen oxides, hydrogen bromide, and carbon oxides in a fire situation
Protective Equipment: Wear self-contained breathing apparatus and protective clothing during fire response
Special Firefighting Instructions: Move containers away from fire area when safe; avoid inhaling combustion products
Combustion Products: CO, CO2, NOx, hydrogen bromide
Personal Precautions: Avoid generating dust, provide adequate ventilation, use suitable personal protective equipment such as gloves, goggles, and lab coat
Environmental Precautions: Prevent entry into drains, soil, or watercourses; report major spills to local authorities as required
Clean-Up Methods: Absorb small spills using an inert material like dry sand or vermiculite, sweep up and transfer to a suitable container; decontaminate area with water and detergent, ensure proper disposal
Protective Measures: Isolate spill area, restrict access to trained personnel only
Handling: Use only in well-ventilated areas, avoid dust formation, avoid direct physical contact by employing gloves and eye protection; do not breathe dust or vapors
Hygiene Practices: Wash hands and any exposed skin thoroughly after handling, avoid eating, drinking, or smoking while using the chemical
Storage: Store in a cool, dry, well-ventilated place; keep the container tightly sealed, protect from moisture and light; store away from strong acids, bases, and oxidizing agents
Specific Storage Considerations: Use sealed, moisture-resistant containers; segregate from incompatible materials
Engineering Controls: Use chemical fume hood or local exhaust ventilation for all laboratory handling; avoid open bench work for large quantities
Personal Protective Equipment: Nitrile gloves, safety goggles, laboratory coat, close-toed shoes
Respiratory Protection: Use dust mask or respirator (NIOSH-approved) if ventilation is inadequate or risk of airborne exposure exists
Environmental Control: Prevent chemical from entering drains, soil, or water bodies; use spill containment if necessary
Exposure Limits: No specific occupational exposure limits set; treat exposure as for nuisance dust or irritant
Physical State: Solid or viscous liquid at room temperature (appearance may vary with hygroscopicity)
Color: White to pale yellow powder or crystal
Odor: Slight chemical or ammoniacal smell
Molecular Weight: 235.12 g/mol
Melting Point: 60-110°C (range based on purity and water content)
Boiling Point: Decomposes before boiling
Flash Point: >100°C (estimated, not easily flammable)
Solubility: Readily soluble in water; soluble in polar organic solvents (e.g., methanol, ethanol)
Vapor Pressure: Negligible at ambient conditions
Density: Approximately 1.20-1.25 g/cm³
pH (aqueous solution): Near neutral (6-8)
Viscosity: Moderate to high for liquid or molten phase
Chemical Stability: Stable under recommended storage and ordinary handling conditions
Reactivity: Hygroscopic; reacts with water to form ionic solution
Incompatible Materials: Strong oxidizing agents, strong acids and bases
Hazardous Decomposition Products: On combustion or decomposition, releases hydrogen bromide, nitrogen oxides, and carbon oxides
Hazardous Polymerization: Not known to occur
Other Stability Concerns: Exposure to air and moisture may cause material to clump or degrade; store with desiccant for maximum shelf life
Acute Toxicity: Limited data; material may cause mild irritation to skin or eyes; ingestion can cause gastrointestinal disturbance
Inhalation Effects: May cause headache, dizziness, or respiratory tract irritation from dust
Skin Corrosion/Irritation: May trigger mild irritation, rash, or dryness with prolonged exposure
Eye Damage/Irritation: Can cause watering, redness, or minor chemical injury
Sensitization: No reliable evidence for sensitization, yet repeated contact may increase irritation risk
Chronic Toxicity: No chronic toxicity documented for this compound; avoid unnecessary exposure
Carcinogenicity/Mutagenicity/Reproductive Effects: No evidence of carcinogenic, mutagenic, or teratogenic effects; precautions still advised due to lack of long-term studies
Routes of Exposure: Inhalation, ingestion, skin and eye contact
Ecotoxicity: Data limited, yet similar alkylimidazolium compounds show aquatic toxicity at moderate concentrations; caution with waterways
Persistence and Degradability: Appears persistent in the environment due to ionic structure; slow degradation
Bioaccumulation Potential: Not expected to bioaccumulate significantly, molecular structure limits lipid solubility
Mobility in Soil: High solubility; can migrate in the aqueous phase if released
Other Adverse Effects: Prevent uncontrolled discharge to the environment, especially aquatic systems, without proper treatment
