Notes to Physician: Treat symptomatically; no specific antidote identified
Suitable Extinguishing Media: Use water spray, dry chemical, carbon dioxide, or foam
Special Hazards: May emit hazardous fumes of carbon oxides, nitrogen oxides, sulfur oxides, and hydrogen fluoride upon combustion
Protective Equipment: Firefighters should wear full protective clothing and self-contained breathing apparatus
Advice for Firefighters: Approach fire from upwind side, prevent runoff to drains or open waterways, cool containers with water spray
Personal Precautions: Use adequate ventilation, avoid breathing dust or vapor, prevent skin and eye contact, wear appropriate personal protective equipment
Environmental Precautions: Prevent further leakage or spillage, do not let product enter drains, surface water, or soil
Methods for Cleanup: Absorb with inert material (sand, earth), place in suitable disposal container, ventilate area, wash spill site with appropriate cleaning agents and water
Handling: Avoid contact with skin, eyes and clothing, handle in well-ventilated area, do not breathe fumes or vapors, use protective equipment
Storage Conditions: Store in tightly closed container, keep in a cool, dry, well-ventilated place, protect from moisture and incompatible substances such as strong oxidizers and strong bases
Incompatibilities: Strong oxidizing agents, strong bases, acids may cause rapid decomposition or hazardous reactions
Control Parameters: No established exposure limits, use general district workplace exposure guidelines for chemicals
Engineering Controls: Use fume hood or local exhaust ventilation at point of vapor or mist formation
Personal Protective Equipment: Chemical-resistant gloves (nitrile or neoprene), safety goggles, protective lab coat, if risk of inhalation, use NIOSH-approved respirator
Hygiene Measures: Do not eat, drink or smoke near area, wash hands and face after handling

Odor: Slight, aromatic or sulfur odor
pH: Not available
Melting Point: Approx. 10-20°C
Boiling Point: Decomposes before boiling
Flash Point: >150°C (estimate, not flammable but may combust at high temperature)
Solubility: Miscible in water and polar organic solvents
Vapor Pressure: Negligible at room temperature
Density: Around 1.4-1.5 g/cm³ at 25°C
Chemical Stability: Stable under recommended storage and handling conditions
Conditions to Avoid: High temperatures, strong oxidizing or reducing agents, direct sunlight
Incompatible Materials: Strong bases, oxidizers, acids can trigger hazardous decomposition
Hazardous Decomposition Products: May release carbon oxides, sulfur oxides, nitrogen oxides, hydrogen fluoride
Polymerization: Not expected under standard conditions
Acute Toxicity: Data limited, expect low acute toxicity based on structure; ingestion or skin absorption may cause irritation
Skin Irritation: May cause redness, swelling or discomfort
Eye Irritation: Exposure may lead to pain, watering or redness
Inhalation: Misting can irritate respiratory tract
Chronic Effects: No comprehensive studies reported, use caution and limit exposure
Carcinogenicity/Mutagenicity: No data available; chemical not listed as carcinogen by NTP, IARC, or OSHA based on available literature
Ecotoxicity: Information not widely available, ionic liquids have potential toxicity for aquatic organisms; release to environment should be minimized
Persistence and Degradability: Likely degradable by hydrolysis and photolysis over time, exact data unavailable
Bioaccumulation Potential: No significant risk expected, low log Kow anticipated, but data lacking
Mobility in Soil: High solubility suggests mobility, risk of groundwater contamination must be monitored
Other Hazardous Effects: No known significant effects or critical hazards, but best practice advises caution
Disposal Methods: Dispose of in accordance with local, regional, and national regulations; incineration in licensed facility usually preferred
Contaminated Packaging: Treat as chemical waste; triple rinse and remove labels before disposal
