Impurities: Trace residuals from production, unlikely to pose additional hazards if handled as directed
Eye Contact: Flush with plenty of water, keep eyelids open, seek medical help for persistent irritation
Skin Contact: Remove contaminated clothing, wash skin with soap and water, obtain medical advice if irritation develops
Inhalation: Move to fresh air promptly, monitor for symptoms, get professional medical attention if discomfort occurs
Ingestion: Rinse mouth with water, do not induce vomiting, seek immediate medical attention, show safety data sheet if possible
Further Notes: Symptomatic supportive treatment is recommended, inform physician of nature of exposure for targeted care
Suitable Extinguishing Media: Dry chemical, carbon dioxide, foam, water spray if safe
Unsuitable Extinguishing Media: High pressure water jets if chemical scattered
Specific Hazards: Intense heat decomposes chemical, giving off toxic nitrogen and bromine-containing gases
Firefighter Protection: Wear full firefighting gear and self-contained breathing apparatus, avoid inhaling fumes
Special Precautions: Keep containers cool by spraying water mist, consider downwind evacuation if large amounts burn
Personal Precautions: Wear gloves, eye protection, avoid dust, use P2-grade respirator if dust risk present
Environmental Precautions: Do not release to drains, avoid ground and waterways contamination, inform authorities of significant spills
Methods for Cleanup: Scoop up spillage with non-sparking tools, store in closed container for disposal, ventilate area, wash site with water if safe for environment
Secondary Actions: Dispose of cleaning implements safely, avoid recontamination
Safe Handling: Handle in well-ventilated area, wear lab coat, gloves, and goggles, avoid contact with incompatible materials (strong oxidizing agents, acids)
Hygiene Measures: Prohibit food and drink where chemical handled, cleanse hands after use, check for skin/fabric contamination before leaving work area
Storage Requirements: Secure airtight container, keep in dry and cool storage, avoid direct sunlight and moisture exposure, restrict access to authorized staff
Incompatibilities: Do not store with oxidizers, strong acids, or combustible compounds
Storage Temperature: Room temperature suggested unless otherwise specified by supplier documentation
Engineering Controls: Use fume hood where practical, local exhaust recommended for powder handling, maintain air exchange
Eye Protection: Safety goggles or face shield
Skin Protection: Wear chemical-resistant gloves, museum-grade nitrile or neoprene preferred
Respiratory Protection: P2 or equivalent dust respirator if ventilation insufficient or powder forms
Workplace Monitoring: Periodic air quality monitoring in labs, evaluate workplace routes for exposures
Additional Protection: Wear protective clothing, apron, and closed footwear, establish spill protocols and ready access to eyewash or shower station
Physical State: Solid
Appearance: White to off-white crystalline powder
Odor: Odorless
pH: Neutral in aqueous solution
Melting Point: Approximately 190-195°C
Boiling Point: Decomposes before boiling
Solubility in Water: Highly soluble
Density: About 1.25 g/cm³
Vapor Pressure: Not significant at ambient temperature
Flash Point: Not flammable under common circumstances
Partition Coefficient: Log Pow data not widely available; presumed low bioaccumulation due to ionic nature
Chemical Stability: Stable under recommended storage and handling conditions
Reactivity: May react with strong oxidizers, acids, bases
Decomposition Products: Thermal breakdown releases hydrogen bromide, organic vapors, possible nitrogen oxides
Hazardous Reactions: Violent reaction unlikely, maintain separation from other reactive chemicals
Instability Conditions: Moisture, extreme heat, direct sunlight
Polymerization: Not expected to undergo hazardous polymerization
Acute Toxicity: Oral LD50 (rat): above 200 mg/kg (data limited, extrapolated from related pyrrolidinium salts)
Skin Corrosion/Irritation: Likely to irritate skin, especially on prolonged or repeated exposure
Serious Eye Damage/Irritation: Causes eye irritation, risk greater if dust contacts eyes
Respiratory Sensitization: Not well documented, avoid inhalation of dust
Carcinogenicity: No definitive studies, but not listed by IARC, NTP, or OSHA as carcinogen
Mutagenicity: No significant data available
Reproductive Toxicity: Not enough evidence for claim of reproductive harm or developmental risk
Chronic Effects: Repeated exposure may cause skin, respiratory, or eye irritation; do not expose individuals with allergies or sensitive skin
Ecotoxicity: Not acutely hazardous to aquatic life in small quantities, but discharge to water should be avoided
Persistence and Degradability: Limited environmental data, ionic compounds often show moderate persistence
Bioaccumulation Potential: Presumed low due to charged structure
Mobility in Soil: Likely mobile, may leach with water seepage
Other Adverse Effects: No ozone-depleting potential, avoid large accidental environmental release
Waste Handling: Collect residue in labeled, sealed containers, minimize dust
Disposal Methods: Incinerate in permitted chemical waste facility or dispose in licensed landfill; follow local, regional, national regulations
Container Disposal: Triple rinse before recycling or disposal, puncture to prevent reuse once decontaminated
Additional Instructions: Do not discharge to public sewer or natural waters, manage contaminated cleaning materials as hazardous waste
UN Number: Not classified as hazardous for ground/air/sea transport
Proper Shipping Name: N-Propyl-N-Methylpyrrolidinium Bromide
Transport Hazard Class: Not a dangerous good under UN Model Regulations
