General Advice: Move individual away from exposure and ensure access to fresh air
If Inhaled: Relocate to an area with fresh, uncontaminated air; seek medical attention for ongoing discomfort, coughing, or shortness of breath
If On Skin: Wash immediately with soap and water for at least 15 minutes; remove contaminated clothing and launder before reuse
If In Eyes: Flush eyes gently with water for at least 15 minutes; hold eyelids open during rinsing; consult ophthalmologist if irritation or symptoms persist
If Swallowed: Rinse mouth thoroughly; do not induce vomiting; contact physician or poison control center as soon as possible
Important Symptoms: Burning, redness, itching, irritation of contact sites; respiratory irritation; gastrointestinal distress if ingested
Suitable Extinguishing Media: Use foam, dry powder, carbon dioxide, or water spray for small fires
Unsuitable Extinguishing Media: Water jet direct stream may spread hazard
Specific Hazards: Combustion releases toxic nitrogen oxides, imidazole derivatives, and corrosive fumes
Protective Equipment for Firefighters: Wear self-contained breathing apparatus and fire protective gear
Firefighting Procedures: Cool containers with water, keep upwind, avoid inhalation of fumes
Personal Precautions: Wear appropriate personal protective equipment including gloves, goggles, and mask
Environmental Precautions: Prevent entry into drains, sewers, waterways, soil
Methods for Clean-Up: Absorb loose material with inert absorbent (vermiculite, sand), place in waste container for proper disposal
Decontamination: Wash affected surface with soapy water; ventilate area; dispose cleanup materials according to local regulations
Special Handling of Spills: For large release, evacuate area, consult hazardous materials team
Precautions for Safe Handling: Avoid inhalation of vapor, mist, or dust; prevent skin and eye contact; use only in well-ventilated areas; keep containers tightly closed when not in use; practice good industrial hygiene
Storage Requirements: Store in sealed containers in a cool, dry, well-ventilated area; protect from direct sunlight and incompatible substances such as strong acids and oxidizers
Special Sensitivities: Moisture sensitive, store away from water and humid conditions; avoid ignition sources; label containers clearly
Occupational Exposure Limits: No established ACGIH/TLV or OSHA PEL values; minimize exposure as best practice
Engineering Controls: Use with local exhaust or general room ventilation; handle in chemical fume hood when practical
Personal Protective Equipment (PPE): Use chemical-resistant gloves (nitrile recommended); wear safety goggles or face shield; don long-sleeved clothing and lab coat; use respiratory protection (NIOSH-approved mask) if airborne concentrations present
Hygiene Measures: Wash thoroughly after handling and before eating, drinking, or smoking; remove contaminated clothing
Appearance: White to off-white powder or crystalline solid
Odor: Slight, characteristic
Melting Point: 42-44°C (107.6-111.2°F)
Boiling Point: Decomposes prior to boiling
Vapor Pressure: Negligible at ambient temperature
Solubility: Low solubility in water; soluble in organic solvents (ethanol, acetone, chloroform)
pH: Not determined in water due to low solubility; basic in nature
Partition Coefficient (Log Pow): Estimated >6 (hydrophobic)
Density: ~0.92 g/cm³ at 20°C
Decomposition Temperature: Above 180°C with generation of toxic fumes
Chemical Stability: Stable under normal laboratory conditions; sensitive to strong acids and oxidizers
Reactivity: May react with strong oxidizing agents, acid chlorides, and acid anhydrides
Hazardous Decomposition Products: Burns to produce nitrogen oxides, carbon oxides, imidazole vapors
Conditions to Avoid: Prolonged exposure to heat, moisture, strong acids, and sunlight
Polymerization: No hazardous polymerization expected
Routes of Exposure: Inhalation, skin and eye contact, ingestion
Acute Effects: Harmful if ingested or inhaled; may cause mouth, throat, gastric irritation; strong skin/eye irritant
Chronic Effects: Prolonged exposure could lead to dermatitis, potential sensitization reactions
LD50 (Oral, rat): Approximate values suggest 350-850 mg/kg (estimation based on close imidazole derivatives)
Carcinogenicity: No evidence in available data
Mutagenicity: Not classified as mutagenic from available studies
Other Health Effects: Irritation, local skin corrosion, possible respiratory discomfort
Aquatic Toxicity: Toxic to aquatic organisms (fish, invertebrates); rapid harmful effects at moderate concentrations
Persistence and Degradability: Not readily biodegradable in standard tests; persistent in soil and sediment possible
Bioaccumulative Potential: Likely to bioaccumulate based on high log Pow
Mobility in Soil: Strong sorption to soil organic matter, low mobility through ground water
Other Environmental Hazards: Avoid release to environment, even small spills present risk to aquatic life
Disposal Methods: Collect material in tightly closed container; incinerate in chemical waste-burning facility; follow local hazardous waste regulations
Contaminated Packaging: Rinse containers thoroughly before recycling or disposal according to regulations
Precautions: Do not allow run-off into drains or sewers; avoid generation of dust or vapors during waste handling
