Common Name: 1-Butylpyridinium Hexafluorophosphate
Chemical Formula: C9H16F6NP
Chemical Family: Ionic liquid
Physical Appearance: Colorless to pale yellow liquid
Odor: Mild or faint, often hard to distinguish without experience
Usage: This salt finds its way into electrochemistry labs and specialty battery research. It stands out in solvents and electrolytes used in advanced technologies.
Hazard Classification: Potentially harmful if inhaled, swallowed, or absorbed through skin
Skin Contact: Irritation possible; redness and itching can linger with repeated exposure
Eye Contact: Moderate irritation; splashes may produce watering and burning
Inhalation: Respiratory discomfort and coughing occur in poorly ventilated areas
Fire Hazard: Non-flammable as a liquid, but decomposition products may cause concern
Environmental Risk: Persistence in aquatic environments raises long-term issues for water life
Acute Toxicity: Data remains limited; caution comes from its chemical relatives
Chemical Identity: 1-Butylpyridinium Hexafluorophosphate
CAS Number: 244615-46-7
Concentration Range: Pure or highly concentrated when provided for research
Impurities: Sometimes slight hydrolysis products, especially with prolonged storage in humid air
Sensitizers: Not typical, but individual sensitivity varies
Skin Exposure: Immediate washing with water and soap stops most irritation
Inhalation: Fresh air and rest; persistent symptoms may require medical attention
Eye Exposure: Rinsing eyes for several minutes with clean water brings quick relief
Ingestion: Rinsing the mouth, drinking water to dilute, and rapid medical advice reduce harm
General: Prompt response outweighs hesitation; knowing protocols means less risk for those in the lab
Suitable Extinguishing Media: Carbon dioxide, dry chemical, or foam protect surrounding materials
Hazardous Combustion Products: Upon burning, toxic fluorine-containing fumes develop
Protective Equipment: Firefighters need full protective gear including self-contained breathing apparatus
Fire Behavior: Not prone to ignition, yet breakdown products can complicate clean-up
Evacuation: Nearby areas sometimes need clearing if lots of material burns
Personal Protection: Gloves, goggles, and lab coats set the standard for safety
Ventilation: Open windows or fume hoods dissipate fumes fast
Spill Cleanup: Absorb with inert material such as sand or diatomaceous earth
Disposal: Collect into suitable waste containers for specialized disposal
Environmental Precautions: Prevention of entry into waterways saves hassle for downstream systems
Handling: Small doses, careful transfer, and minimizing splashes keep risk down
Storage Temperature: Cool, dry, and well-ventilated space preserves product integrity
Container Material: Use glass or compatible plastics instead of metals
Incompatibilities: Avoid contact with moisture and strong oxidizers
Shelf Life: Extended if sealed tightly and light is limited
Engineering Controls: Fume hoods or local exhaust help keep air clear
Personal Protection: Nitrile gloves, chemical splash goggles, and lab coats remain essential
Respiratory Protection: Needed in high vapor situations, but normally avoided with proper ventilation
Hygiene: Handwashing before eating or touching the face reduces risk
Environmental Controls: Closed system handling lowers emissions to work areas
Appearance: Oily liquid, often clear with a faint yellow hue
Melting Point: Typically below room temperature, doesn’t freeze easily
Boiling Point: Decomposition tends to occur before boiling can be observed
Density: Higher than water, usually between 1.2–1.4 g/cm³
Solubility: Insoluble in water; mixes well with polar organic solvents
Odor Threshold: Hard to determine due to faint scent
Vapor Pressure: Low, vapor does not rise quickly under normal conditions
Chemical Stability: Stable if kept dry and away from open air
Conditions to Avoid: Humidity, moisture, and high temperatures spark decomposition
Hazardous Decomposition Products: Hydrolysis can free corrosive acids, especially HF (hydrogen fluoride)
Polymerization: No known risk in usual storage or application
Reactivity: Unhappy with strong bases and oxidizing agents
Acute Risks: Irritates skin, eyes, and airways
Chronic Exposure: Long-term data lacks detail but caution tells us to avoid repeated contact
Sensitization: Not commonly reported, but allergy risk exists
Mutagenicity and Carcinogenicity: No specific evidence points to genetic or cancer risks for this salt
Medical Conditions Aggravated: Respiratory conditions may get worse after inhalation exposure
Aquatic Toxicity: Ionic liquids accumulate in ecosystem sediment and water, threatening aquatic critters
Persistence and Degradability: Chemical structure resists breakdown, so contamination lingers
Potential for Bioaccumulation: Unknown for this specific compound, but relatives show some risk
Mobility: Tends to bind or sink instead of float, increasing sediment impact
Emissions: Poor disposal sends ions downstream, sometimes into food chains
Waste Handling: Liquid should never be poured down the drain
Incineration: Specialist facilities required to avoid toxic off-gas production
Regulatory Guidelines: Obey chemical waste regulations for ionic liquids; consult local protocols
Container Disposal: Decontamination first, chemical disposal next
Reuse and Recycling: Rarely justified in small-scale use due to contamination risk
Shipping Name: Often shipped under specialized labeling for safe transport
Hazard Labels: “Harmful” or “irritant” markings common in shipment
Packing Requirements: Leakproof, sealed, and cushioned containers
Air, Road, Rail Restrictions: Some regions prohibit certain ionic liquids in passenger aircraft
Spill Response in Transit: Emergency kits, absorbent materials, and personal protective equipment routinely accompany shipments
Classification: Listed under various chemical management standards due to potential risks
Workplace Limits: No official occupational exposure limits set for this compound yet
Environmental Controls: Discharge into the environment discouraged under pollution laws
Right to Know: Users have a legal and ethical obligation to train staff and communicate hazards
Documentation: Keeping current safety information on hand, including risk assessments, supports both compliance and peace of mind
