First Aid Measures

Eye Contact: Immediately flush eyes with plenty of water for at least 15 minutes, lifting upper and lower eyelids. Seek medical attention without delay.
Skin Contact: Remove contaminated clothing and wash affected area with soap and water. If irritation persists, seek medical help.
Inhalation: Move person to fresh air. If not breathing, give artificial respiration or oxygen by trained personnel. Contact emergency services.
Ingestion: Rinse mouth thoroughly with water, do not induce vomiting. Seek medical advice immediately.
Most Important Symptoms: Burning sensation, redness, coughing, gastrointestinal discomfort, and possible allergic reactions. Prompt treatment limits lasting effects.

Fire-Fighting Measures

Suitable Extinguishing Media: Use water spray, alcohol-resistant foam, dry chemical powder, or carbon dioxide.
Specific Hazards: Heating may produce toxic fumes including nitrogen oxides, hydrogen bromide, and carbon oxides.
Special Protective Equipment for Firefighters: Wear full protective gear and self-contained breathing apparatus.
Precautions: Approach fire from upwind direction. Contain run-off to prevent environmental contamination.
Combustion Products: Dense, irritating smoke may develop. Thermal decomposition releases hazardous vapors; proper ventilation reduces exposure.

Accidental Release Measures

Personal Precautions: Evacuate area; ventilate well. Wear chemical-resistant gloves, long-sleeved clothing, splash-proof goggles, and a particulate respirator.
Spill Cleanup Method: Scoop up solid material carefully. Collect and place in labeled waste container for disposal. Rinse residue with plenty of water. Prevent spillage from entering drains.
Environmental Precautions: Prevent further leakage or spillage if safe to do so. Notify authorities if large quantities enter waterways.
Decontamination: Wash spill site after cleanup is finished. Use absorbents designed for organic and halogenated compounds for best removal.

Handling and Storage

Handling Practices: Handle using appropriate engineering controls such as fume hoods and local exhaust. Avoid formation of dust and aerosols. Avoid direct contact and inhalation.
Storage Requirements: Store in tightly closed containers away from moisture, heat, and incompatible materials. Keep in cool, dry, well-ventilated location.
Incompatible Materials: Store away from strong oxidizing agents, acids, bases, and reducing agents. Avoid prolonged exposure to light.
Hygiene Measures: Wash hands thoroughly after handling. Remove and wash contaminated clothing before reuse.

Exposure Controls and Personal Protection

Exposure Limits: No occupational exposure limit established for this compound. Minimize exposure as a precaution.
Engineering Controls: Work in chemical fume hood; use localized ventilation as required.
Personal Protective Equipment: Chemical splash goggles, protective gloves (nitrile recommended), lab coat, and certified particulate respirator if inhalation risk exists.
Hygiene: Do not eat, drink, or smoke during handling. Immediately wash exposed areas after use.
Environmental Controls: Implement containment to prevent release to environment. Regular checks on ventilation systems reduce risk.

Physical and Chemical Properties

Appearance: Off-white to pale yellow solid
Odor: Slight, not characteristic
Melting Point: Typically 180-190°C
Boiling Point: Decomposes before boiling
Solubility: Readily soluble in water and polar organic solvents
Density: 1.7–1.9 g/cm³ (estimated)
pH: Neutral to slightly acidic (aqueous solution)
Other Data: Hygroscopic; absorbs water from air. Stable under recommended storage, can degrade under UV or strong heat.

Stability and Reactivity

Chemical Stability: Stable under normal temperature and pressure.
Hazardous Reactions: May react with strong bases and oxidizers. Prolonged exposure to moisture or sunlight can increase risk of degradation.
Decomposition Products: Hydrogen bromide, carbon monoxide, carbon dioxide, nitrogen oxides.
Conditions to Avoid: Excess moisture, prolonged elevated temperatures, exposure to direct sunlight.
Polymerization: No dangerous polymerization expected under normal conditions.

Toxicological Information

Acute Toxicity: Data on exact Lethal Dose (LD50) unavailable; similar compounds show moderate oral and dermal toxicity in animal studies.
Skin/Eye Contact: Causes moderate to severe irritation; possible eye damage on prolonged exposure.
Inhalation: Dust may cause respiratory irritation, coughing, sore throat, shortness of breath.
Chronic Effects: Prolonged or repetitive exposure may cause skin sensitization and possible effects on nervous and digestive systems.
Carcinogenicity/Mutagenicity: No IARC, NTP, or OSHA classification; chronic toxicity data not fully established.
Additional Data: Data gaps exist; proper protection and careful handling minimize risk.

Ecological Information

Toxicity to Aquatic Life: Harmful to aquatic organisms, may cause long-lasting adverse effects in aquatic environment.
Biodegradation: Likely to persist based on structure of imidazolium salts and bromide counterion.
Bioaccumulation Potential: Low to moderate, similar to other ionic liquids, though data is limited.
Mobility in Soil: Expected to exhibit moderate mobility due to solubility in water.
Other Adverse Effects: Keep away from soil and natural water sources to limit ecological impact.

Disposal Considerations

Waste Disposal Methods: Dispose of both chemical and contaminated packaging via licensed hazardous waste contractor. Follow national, state, and local environmental regulations.
Special Precautions: Avoid disposal into waterways; consult with regulatory agencies on best disposal practices for bromide-containing ionic compounds.
Contaminated Packaging: Triple rinse containers, puncture, and offer for recycling or disposal as hazardous waste.
Recommended Handling: Segregate waste from general laboratory trash; use clearly labeled waste streams for halogenated organics.

Transport Information

UN Number: Not regulated under most national or international transport codes, though lab-specific bulk shipments may require assessment.
Proper Shipping Name: Chemical, not otherwise specified
Hazard Class: Treat as Class 9 (miscellaneous hazardous material) when shipping in larger quantities.
Packing Group: III (if classified)
Environmental Hazards: Marine pollutant in large spill scenarios, avoid bulk transport near water.
Transport Precautions: Package securely in sealed, non-reactive containers. Prevent shifting and spillage throughout transport.

Regulatory Information

Inventory Lists: Not typically listed on major chemical inventories such as TSCA, EINECS, AICS; research and importation often require approval.
Workplace Regulations: Subject to lab safety plan oversight and hazardous substance controls. Monitor for airborne concentrations if handling frequently.
OSHA/WHMIS/GHS Status: Not specifically regulated, enforce general hazard communication rules and laboratory safety practices.
Labeling Requirements: Label clearly as hazardous, list all precautionary handling and first aid instructions directly on container.
Additional National/Local Rules: Check most recent updates from EPA, REACH, and equivalent authorities before procurement and use. Some regions require environmental risk reporting for brominated compounds.
