Explosion Risk: Not known to form explosive mixtures, but avoid dust clouds and strong oxidizers
Personal Precautions: Restrict area to trained personnel, use gloves, goggles, and protective clothing
Spill Containment: Prevent entry into drains, waterways, or soil, form physical barriers or apply absorbent materials such as sand or inert clay
Cleanup Methods: Scoop up product or absorbent into containers for disposal according to regulations, wash area with plenty of water after removal
Environmental Protection: Notify authorities if large quantities are released to the environment, seek advice for cleanup of significant spills
Decontamination: Ventilate area, avoid direct contact, dispose of contaminated materials responsibly
Safe Handling: Use in well-ventilated laboratory environments, avoid direct skin and eye contact, always wear standard lab PPE (lab coat, nitrile gloves, splash-proof goggles), never eat or drink near workspace
Storage Conditions: Store in tightly sealed containers, keep in cool, dry location away from sunlight and heat, isolate from incompatible chemicals such as oxidizing agents and strong acids
Storage Packaging: Use high-density polyethylene, glass, or compatible plastic containers
Incompatibilities: Do not store beside explosives, oxidizing materials, or food substances
Engineering Controls: Always use a chemical fume hood or ensure local exhaust ventilation
Personal Protective Equipment: Chemical resistant gloves (nitrile preferred), safety goggles, laboratory coat, closed footwear, in some cases face shield
Hygiene Measures: Wash hands thoroughly after handling, remove contaminated clothing before breaks or leaving the laboratory, clean work surfaces after completion
Occupational Exposure Limits: Not established as a workplace chemical hazard at low volumes, practice good laboratory discipline to limit exposure

Odor: Mild aromatic or slightly sweet
Melting Point: Typically below room temperature, often a room-temperature ionic liquid
Boiling Point: Decomposes before boiling, often above 200°C
Density: Approximately 1.1–1.2 g/cm³ (25°C)
Solubility: Readily dissolves in water and organic solvents like methanol, ethanol, and acetone
Viscosity: Moderate to high viscosity depending on temperature
pH: Neutral to slightly acidic in aqueous solution
Flash Point: Not easily flammable, often >150°C
Vapor Pressure: Very low at ambient temperature
Chemical Stability: Stable under normal laboratory conditions
Thermal Decomposition: Decomposes at elevated temperatures, emission of toxic fumes possible
Reactivity: Non-reactive toward most laboratory reagents, incompatible with strong oxidizers and acids
Hazardous Reactions: No hazardous polymerization, avoid heating above decomposition temperature
Conditions to Avoid: Exposure to open flame, strong UV light, or significant heat
Hazardous Decomposition Products: Nitrogen oxides, sulfur oxides, carbon monoxide/dioxide possible
Acute Toxicity: Oral LD50 data limited, based on related substances expected to be low toxicity at laboratory scale
Skin Irritation: Mild to moderate irritation possible with sustained contact
Eye Irritation: Will cause pain and redness on exposure
Respiratory Effects: Inhalation of aerosols can irritate mucous membranes and throat
Chronic Effects: No established chronic toxicity, avoid repeat or long-term exposure due to lack of data
Carcinogenicity/Mutagenicity: Not listed by IARC, NTP, or OSHA
Other Effects: Not known to cause allergic reactions; toxicity data still under study due to novelty of ionic liquids
Aquatic Toxicity: Harmful to aquatic life, limited data suggests bioaccumulation is minimal, but further studies are ongoing
