Chemical Name: 1-Propyl-3-Methylimidazolium Tetrafluoroborate
Common Name: [PMIM][BF4]
Concentration: ≥ 98 % (by weight)
CAS Number: 174501-64-5
Impurities: Trace solvents or moisture possible; check certificate of analysis for batch specifics
Skin Contact: Remove contaminated clothing; wash exposed skin with plenty of water and mild soap; seek medical attention if irritation develops or persists
Eye Contact: Rinse eyes gently with water for at least 15 minutes, keeping eyelids open; seek medical care immediately
Inhalation: Move person to fresh air; if breathing is difficult or symptoms persist, get medical attention; administer artificial respiration if breathing stops
Ingestion: Do not induce vomiting; rinse mouth with water; provide water to drink if the person is conscious; seek medical advice
Suitable Extinguishing Media: Use carbon dioxide, dry chemical, foam, or water spray depending on surrounding fire
Specific Hazards: Vapors may form combustible mixtures with air; decomposition emits toxic and corrosive fumes (boron trifluoride, hydrogen fluoride, imidazole derivatives)
Protective Equipment: Firefighters use self-contained breathing apparatus, wear chemical protective clothing; avoid inhaling combustion products
Advice: Stay upwind; cool containers exposed to flames with water spray; prevent fire-fighting runoff from entering drains
Personal Precautions: Evacuate unprotected personnel; wear gloves, goggles, and protective clothing; avoid inhalation and skin contact
Environmental Precautions: Prevent spill from reaching waterways, soil, or drains; contain spill with absorbent material (vermiculite, sand, inert material)
Cleanup Methods: Scoop up with non-sparking tools; place in a compatible chemical waste container; ventilate the area; properly label and dispose of collected material; decontaminate area with soap and water
Handling: Work in fume hood; wear appropriate PPE; avoid exposure; do not eat, drink, or smoke while handling; minimize vapor and mist generation
Storage: Keep tightly sealed in original container; store in cool, dry, well-ventilated area away from direct sunlight and incompatible chemicals such as strong acids, strong bases, oxidizers, or moisture
Incompatible Materials: Moisture, acids, bases, oxidizing agents; contact with water may produce hydrofluoric acid
Special Notes: Keep container upright and tightly closed to prevent leaks
Engineering Controls: Use fume hood or local exhaust to minimize airborne concentrations
Personal Protective Equipment (PPE): Chemical-resistant gloves (nitrile or neoprene), safety goggles or face shield, lab coat, closed shoes
Respiratory Protection: Use approved respirators if exposure risk is high or ventilation is inadequate
Environmental Controls: Avoid release to sewer, surface water, or soil; use spill containment where necessary
Occupational Limits: No specific exposure limits determined by OSHA, ACGIH or NIOSH for this compound
Appearance: Colorless-to-pale yellow liquid

Partition Coefficient: No data available
Decomposition Temperature: >200°C
Auto-ignition Temperature: No data available
Chemical Stability: Stable under standard temperatures and pressures if stored properly
Reactivity: Incompatible with strong oxidizers, acids, bases, and moisture; reacts to form toxic gases upon decomposition
Hazardous Decomposition Products: Boron trifluoride, hydrogen fluoride, carbon oxides, imidazole derivatives
Polymerization: Not known to undergo dangerous polymerization
Conditions to Avoid: High temperature, open flames, contact with incompatible materials, exposure to moisture
Acute Toxicity: Oral and skin toxicity data are limited; animal studies suggest low to moderate toxicity
Skin Contact: Irritant; symptoms may include redness, dryness, discomfort
Eye Contact: Causes serious eye irritation; risk of corneal damage exists
Inhalation: Can irritate respiratory tract; high vapor concentrations may cause dizziness, headache, or respiratory discomfort
Chronic Effects: No reliable long-term data; potential for cumulative liver or kidney effects with repeated exposure
Carcinogenicity: Not classified as carcinogenic according to IARC, ACGIH, NTP, or OSHA
Mutagenicity: No evidence from available tests
Reproductive Toxicity: Not established by specific studies
Sensitization: Not known to cause allergic skin reactions
Environmental Fate: Not readily biodegradable; expected to persist in aquatic environments
Aquatic Toxicity: Harmful to aquatic organisms, may cause long-term negative effects in the aquatic environment
Bioaccumulation: Potential for moderate bioaccumulation; specific data limited
Mobility: May migrate in water and soil; ionic liquids often display high solubility in water and organic phases
Other Information: Prevent release to waterways to reduce impact on aquatic life; waste streams require specialized disposal
Waste Treatment Methods: Dispose of at certified hazardous waste facility; do not discharge to drain, waterway, or on land
Contaminated Packaging: Triple-rinse empty containers, then offer for recycling or disposal in accordance with local regulations
