Skin Contact: Wash exposed area with plenty of soap and water for 15 minutes; remove contaminated clothing, consult a physician if irritation persists
Eye Contact: Rinse immediately with flowing water for at least 15 minutes, hold eyelids apart, seek prompt medical attention for persistent discomfort
Inhalation: Move person to fresh air; if breathing is difficult, supply oxygen and get medical aid
Ingestion: Rinse mouth with water; do not induce vomiting; if symptoms develop, contact medical professional
Note to Physician: Symptomatic treatment is recommended since specific antidote does not exist
Suitable Extinguishing Media: Use foam, dry powder, or carbon dioxide; water spray can cool containers but can spread chemicals
Unsuitable Extinguishing Media: Avoid direct water jet as it can cause splattering and potential chemical runoff
Hazardous Decomposition: Possible production of COx, Nx, SOx gases, and methylimidazole or sulfonic acid vapors at high temperature
Protective Equipment: Full protective gear, self-contained breathing apparatus if involved in fire
Firefighting Instructions: Stay upwind, isolate area, use personal protection, remove containers from fire zone if safe, prevent fire spread to sewers or water sources
Personal Precautions: Use gloves, goggles, proper protective clothing; avoid creating dust, ensure adequate ventilation
Environmental Precautions: Prevent product from entering drains, waterways, or soil; alert authorities if widespread contamination might occur
Clean-up Methods: Collect spillage with inert, absorbent material (sand, earth, vermiculite), place in chemical waste container; ventilate affected area; wash down residue with detergent and water, avoid harsh solvents
Disposal: Dispose of according to local, state, and federal regulations; keep waste contained and labeled
Safe Handling: Avoid direct contact, wear personal protective equipment; handle in well-ventilated area or fume hood; do not eat, drink, or smoke during use
Storage Conditions: Store containers tightly closed in dry, cool, and well-ventilated location, out of direct sunlight and away from incompatible substances
Incompatibilities: Strong oxidizing or reducing agents, unexplained mixing with untested chemicals may produce undesirable reactions
Specific Storage Practices: Use secondary containment for large volumes; prevent moisture contact and keep away from contact with food or animal feed
Exposure Limits: No established regulatory exposure limits; treat as general chemical with default workplace safety standards
Engineering Controls: Use local exhaust or appropriate ventilation, especially during transfers, weighing, or open container handling
Personal Protective Equipment: Chemical-resistant gloves (nitrile or neoprene), splash-proof goggles, lab coat or apron; respiratory protection if dust or vapors are likely
Hygiene Practices: Wash thoroughly after handling, remove contaminated clothing, keep work area clean, avoid eating or drinking near product
Appearance: Colorless to pale yellow viscous liquid or crystalline solid
Odor: Mild, nearly odorless; no pronounced volatile character
Melting Point: Typically 60–90°C depending on grade and water content
Boiling Point: Decomposes before boiling well above 200°C
Solubility: Water-soluble, soluble in many polar organic solvents
Vapor Pressure: Extremely low at room temperature, not expected to produce significant vapors
pH: Slightly acidic in solution (typically pH 4–6)
Density: 1.2–1.4 g/cm³ at 25°C
Viscosity: Moderate to high viscosity, depends on water or solvent content
Flash Point: Over 180°C (typically non-flammable in standard use)
Chemical Stability: Stable under recommended conditions, long shelf-life under inert, dry conditions
Reactivity: Not strongly reactive, but contact with strong oxidizers or reactive metals can initiate slow reaction
Hazardous Reactions: None known under standard laboratory conditions; excessive heating can lead to decomposition and releasing irritating gases
Hazardous Decomposition Products: Methanesulfonic acid, methylimidazole, oxides of sulfur, nitrogen, carbon
Polymerization: Will not occur spontaneously
Acute Toxicity: Not acutely toxic by oral, dermal, or inhalation routes in tested mammals, estimated oral LD50 above 2000 mg/kg in rats
Skin Corrosion/Irritation: May cause mild and reversible irritation after prolonged contact; not corrosive
Eye Damage/Irritation: Mild, temporary discomfort may occur but not categorized as damaging
Respiratory Sensitization: Not classified as a sensitizer, but dust or vapor exposure may irritate sensitive individuals
Chronic Effects: No long-term toxicity data available, no evidence of carcinogenicity or reproductive toxicity in available studies
Medical Conditions Aggravated: Preexisting eye, skin, or respiratory conditions could worsen during exposure
Ecotoxicity: Limited data indicates low toxicity to aquatic life, but avoid unnecessary environmental release
Persistence/Degradability: Product resists rapid abiotic breakdown, but some microbial degradation expected over extended periods
Bioaccumulation: Not expected to bioaccumulate due to ionic structure and high water solubility
Mobility: High mobility in water due to solubility, possible migration through soil if large spills occur
Other Adverse Effects: None known, but best practice is to minimize direct entry into environment
Disposal Methods: Treat as chemical waste; incinerate with energy recovery where permitted, or use licensed chemical disposal services
Contaminated Packaging: Rinse empty containers thoroughly before disposal, puncture to prevent reuse, follow local regulations
Waste Codes: Refer to national, regional, or local guidelines; typically not classified as hazardous waste, but confirm with waste contractor
Precautions: Avoid uncontrolled release, improper disposal, or mixing with incompatible materials
UN Number: Not classified as dangerous for most transportation purposes
Transport Hazard Class: Not regulated, does not present major risk under standard shipment conditions
