Protective Equipment: Wear appropriate chemical-resistant gloves, protective goggles, and lab coat
Environmental Precautions: Do not let the product enter drains, soil, or surface water sources
Clean-Up Method: Absorb spills with inert material (sand, vermiculite); collect into containers for disposal; clean area with detergent and water
Safe Handling: Handle in a well-ventilated area, avoid contact with skin, eyes, and clothing; do not ingest or inhale
Storage Conditions: Keep tightly sealed in original container; store in cool, dry, well-ventilated place
Incompatible Materials: Strong oxidizers, strong acids, moisture, sources of ignition
Additional Precautions: Prevent formation of dust or aerosols, use only with adequate ventilation
Engineering Controls: Use local exhaust ventilation, handle in fume hood when possible
Personal Protective Equipment: Wear NIOSH-approved respirators if exposure limits are exceeded; ANSI-approved eye protection (goggles); long sleeves and chemical-resistant gloves
Hygiene Measures: Wash hands, face, and exposed areas after handling; avoid eating, drinking, or smoking during use
Environmental Exposure Controls: Use containment to avoid environmental release; have spill control materials available
Appearance: White to off-white solid (may appear as crystalline powder or flakes)
Odor: Mild, slightly ammoniacal
Odor Threshold: Not determined
pH: Not determined (as supplied, usually neutral to slightly basic in solution)
Melting Point: 50-60°C (approximate)
Boiling Point: Decomposes before boiling

Chemical Stability: Stable under recommended storage and handling conditions
Hazardous Polymerization: Does not occur in normal use
Incompatible Materials: Strong oxidizing agents, strong acids
Conditions to Avoid: Excessive heat, light, and moisture
Hazardous Decomposition Products: Burning produces toxic bromine and nitrogen oxides, carbon monoxide, and carbon dioxide
Routes of Exposure: Inhalation, ingestion, skin or eye contact
Acute Toxicity: Harmful if swallowed, may cause gastrointestinal discomfort; skin contact may produce mild irritation
Chronic Effects: No long-term studies in humans; long-term exposure may cause target organ toxicity
Irritant Effects: Causes moderate to severe eye irritation; mild skin irritation possible
LD50 / LC50: Data not widely available, estimated oral LD50 (rat) > 300 mg/kg
Carcinogenicity: No data to suggest carcinogenic effects in humans
Other Information: No data on mutagenic or reproductive effects; use in research settings should be guided by caution
Ecotoxicity: Harmful to aquatic organisms, may cause long-term adverse effects in aquatic environments
Persistence and Degradability: Not readily biodegradable; tends to persist in the environment
Bioaccumulation Potential: Limited data suggest some potential; ionic liquids may be taken up by aquatic species
Mobility in Soil: Moderately mobile in water, attenuated by soil-binding
Other Adverse Effects: Avoid release to surface waters or sewage; ionic character increases risk to aquatic species
Disposal Techniques: Dispose of in accordance with local, regional, and national regulations; incineration may be appropriate under controlled conditions
