First Aid Measures

Inhalation: Move to fresh air, seek medical attention if symptoms develop like throat irritation or coughing
Skin Contact: Wash thoroughly with soap and water, remove contaminated clothing, seek medical advice if rash or irritation persists
Eye Contact: Rinse immediately for several minutes with plenty of water, lift eyelids to ensure full rinsing, consult physician if discomfort continues
Ingestion: Rinse mouth, seek immediate medical assistance, do not induce vomiting unless instructed by healthcare professional
Symptom Treatment: Treat symptoms as they appear, monitor for respiratory distress or allergic reaction

Fire-Fighting Measures

Suitable Extinguishing Media: Use dry chemical powder, carbon dioxide, alcohol-resistant foam for small and localized fire sources
Unsuitable Media: Do not use direct water streams on burning chemical—risk of spreading or runoff
Hazardous Combustion Products: Irritating gases and vapors such as nitrogen oxides, imidazole decomposition products, hydrogen chloride gas
Protective Equipment for Firefighters: Standard self-contained breathing apparatus, full protective gear to avoid contact or inhalation of decomposition fumes
Additional Advice: Evacuate area, control runoff, avoid inhaling smoke or vapors

Accidental Release Measures

Personal Precautions: Use gloves, goggles, laboratory coat, ventilate spill area to avoid inhalation of dust or vapor
Environmental Precautions: Prevent from entering drains, soil, or water bodies, contain spill with inert absorbents
Cleanup Procedures: Absorb with sand, vermiculite, or suitable material, sweep up and place in closed containers for disposal, wash spill site after material pickup
Disposal Method: Follow local, regional, and national regulations for chemical waste

Handling and Storage

Handling: Work with this compound in well-ventilated settings or under chemical fume hood, avoid skin and eye contact at all stages, never eat or drink near chemicals, use proper labeling and secondary containment
Storage: Keep in tightly closed original containers, store at room temperature below 25°C, keep away from moisture, acids, strong oxidizers, incompatible organics, protect from direct sunlight
Storage Area Requirements: Use designated corrosive or chemical storage cabinets, post hazard signage, restrict access to trained personnel

Exposure Controls and Personal Protection

Engineering Controls: Chemical fume hood or dedicated extraction for any weighing or transfer steps, dedicated spill kits nearby, eye wash and emergency shower stations within reach
Exposure Limit Values: No established regulatory exposure limits, good practices dictate to minimize any airborne or dermal exposure
Personal Protection: Gloves (nitrile or butyl rubber), safety goggles or full shield, chemical-resistant laboratory coat, closed footwear
Hygiene Measures: Wash hands before breaks and after handling, do not touch face, monitor PPE for visible damage or contamination

Physical and Chemical Properties

Physical State: Usually present as a white to off-white crystalline solid; in some climates may be a viscous liquid at laboratory temperatures
Odor: Mild, may have faint amine or salt-like odor
Melting Point: Typical range 120-180°C, some batches vary with synthesis purity
Boiling Point: Not well-defined, decomposes before boiling
Solubility: Fully soluble in water, common polar solvents including methanol and DMSO
pH: Aqueous solutions tend to have mildly acidic pH due to carboxyethyl group
Vapor Pressure: Negligible at standard conditions, ionic nature prevents significant vapor formation
Density: Ranges 1.2 – 1.3 g/cm³ in solid or concentrated liquid
Other data: Not flammable under ambient air, may decompose to irritating gases if heated strongly, highly hygroscopic (absorbs water from air)

Stability and Reactivity

Chemical Stability: Stable under typical storage and laboratory use conditions, protect from strong acids, bases, oxidizers
Incompatible Materials: Do not mix with strong reducing agents, organic acids, or strong bases, avoid contact with aluminum, magnesium
Decomposition Products: May give off toxic fumes including nitric oxides, carbon monoxide, imidazole derivatives, hydrogen chloride on heating or combustion
Conditions to Avoid: Keep away from heat sources, open flames, moisture, and direct sunlight for long-term storage

Toxicological Information

Acute Toxicity: Oral LD50 not fully established, but classified as toxic on ingestion based on structure and similar ionic liquids
Skin Irritation: Direct contact expected to produce mild to moderate irritation based on cationic imidazolium group
Eye Irritation: Can cause burning, pain, tearing on splashes
Inhalation Effects: Dusts or aerosols may irritate upper respiratory tract, avoid inhaling any form of powder or mist
Sensitization: No established evidence for sensitization, caution advised for repeated exposures
Chronic Effects: Limited data, not known to be carcinogenic or mutagenic, repeated exposure may cause dermatitis or eye injury

Ecological Information

Aquatic Toxicity: No standardized data, ionic liquids often toxic to aquatic organisms, strong recommendation not to release into waterways
Persistence and Degradability: Ionic liquids sometimes show persistence, slow to degrade in standard wastewater treatment
Bioaccumulative Potential: Low to moderate based on structure, unknown for this specific compound
Mobility in Soil: Likely mobile in water and soil due to high solubility, may contaminate groundwater if released
Other Adverse Effects: Use containment to limit release, environmental fate studies are lacking

Disposal Considerations

Waste Treatment Methods: Gather all spills and contaminated disposables in closable, chemically-resistant containers, hand over to licensed hazardous waste handler
Incineration: Permitted by approved chemical incinerators with afterburner and scrubber; do not incinerate in regular waste facilities
Container Disposal: Triple rinse empty containers, puncture and dispose as hazardous lab material to prevent reuse
Disposal Restrictions: Never discharge to sewer, stormwater, or natural environments; comply with local, regional, national laws
