Molecular Weight: 158.20 g/mol
Inhalation: Move affected person to fresh air; if symptoms develop, seek medical help; if breathing becomes difficult, give oxygen and consult doctor immediately
Skin Contact: Rinse skin thoroughly with running water and soap for at least 15 minutes; remove contaminated clothing and wash before reuse; medical attention recommended for redness or irritation
Eye Contact: Rinse eyes with plenty of water for at least 15 minutes keeping eyelids open; prompt medical attention for persistent pain or irritation
Ingestion: Rinse mouth with water; do not induce vomiting; seek professional medical help
Most Important Symptoms: Burning sensation, redness, coughing, difficulty breathing if exposed in large amounts
Suitable Extinguishing Media: Water spray, alcohol resistant foam, dry chemical powder, carbon dioxide
Unsuitable Extinguishing Media: Direct water jet, which may spread fire contamination
Specific Hazards: Burning produces irritating and toxic fumes including nitrogen oxides, carbon monoxide, carbon dioxide
Special Protective Equipment: Firefighters need full protective clothing and self-contained breathing apparatus
Fire Precautions: Cool containers with water spray if exposed to flame; move containers from fire area if safe
Explosion Data: Dusts are not expected to form explosive mixtures, but always evaluate local risks
Personal Precautions: Use protective equipment such as gloves, goggles, and respiratory protection; keep unprotected personnel away
Environmental Precautions: Prevent further leakage or spillage; do not allow to enter drains, surface or ground water; consider containment to minimize environmental impact
Methods for Clean-Up: Small spills: absorb with inert material (sand, earth), place into chemical waste containers for disposal; large spills: contain and collect, ventilate area, dispose in accordance with local and national regulations; ventilate and wash spill site after material pickup is complete
Precautions for Safe Handling: Handle in a well-ventilated area; avoid contact with skin, eyes, and clothing; do not breathe dust or vapors; wash hands thoroughly after handling; use appropriate protective equipment for all operations
Storage Conditions: Store in tightly closed containers in a cool, dry, ventilated area; keep away from incompatible substances such as strong oxidizing agents; store away from food or drink to avoid accidental ingestion; check container integrity regularly to spot leaks or corrosion
Other Information: Shelf life depends on storage temperature and packaging integrity; avoid open flames and heat sources
Occupational Exposure Limits: No established limits for N-Benzylimidazole; handle as a chemical of unknown chronic toxicity
Engineering Controls: Use exhaust ventilation and local fume hoods; provide eyewash stations and safety showers in working areas
PPE: Chemical splash goggles, laboratory gloves (nitrile, PVC), long-sleeved protective garments, closed footwear
Respiratory Protection: If ventilation is inadequate, use a NIOSH or EN-approved respirator
Hygiene Measures: Remove contaminated clothing; do not eat, drink or smoke while handling; wash hands thoroughly after handling; proper disposal of cleaning materials
Appearance: White to off-white crystalline powder
Odor: Slight aromatic odor
Melting Point: 76–79°C
Boiling Point: 344°C (decomposes)
Flash Point: 166°C (closed cup, approximate)
Solubility: Slightly soluble in water; soluble in many organic solvents (e.g., ethanol, acetone)
Vapor Pressure: Not significant at room temperature
Density: 1.13 g/cm³
pH: Weakly basic in aqueous solution
Partition Coefficient (log Kow): 1.6 (estimated)
Chemical Stability: Stable under normal storage conditions; avoid strong heat, acids and oxidizers
Incompatible Materials: Strong oxidizing agents, strong acids
Decomposition Products: Toxic fumes of nitrogen oxides, carbon monoxide, carbon dioxide, benzyl derivatives
Conditions to Avoid: Prolonged exposure to light, high temperature, open flames
Hazardous Polymerization: Not reported
Acute Toxicity (Oral LD50): Data limited, estimated rat LD50 > 500 mg/kg
Skin Corrosion/Irritation: May cause mild to moderate skin irritation based on experience with related imidazoles
Serious Eye Damage/Irritation: Causes inflammation and irritation
Respiratory Sensitization: Could trigger irritation on prolonged exposure
Chronic Effects: Chronic exposure data is minimal; liver and kidney stress observed in some animal studies
Carcinogenicity, Mutagenicity, Reproductive Toxicity: Not classified due to insufficient data, nothing on major lists
Other Information: Causes gastrointestinal discomfort if ingested, including nausea or abdominal pain
Ecotoxicity: Limited direct data; related compounds potentially harmful to aquatic life
Persistence and Degradability: Expected to degrade slowly in the environment; not highly persistent but potential for soil and water contamination near industrial sources
Bioaccumulation Potential: Low to moderate based on structural characteristics, log Kow ca. 1.6
Mobility in Soil: Likely has moderate mobility due to solubility in organic solvents
Other Adverse Effects: None established, caution recommended to avoid release to environment
Waste Treatment Methods: Chemical wastes must be collected in sealed, labeled containers for authorized hazardous chemical disposal
Disposal of Packaging: Containers should be triple rinsed and disposed of at approved facilities
Sewage Disposal: Avoid discharge into drains, water courses, or the ground
Special Precautions: Consult local, state, and national regulations for waste disposal requirements and best practices for chemical containment
Recycling: Not recommended except through licensed chemical waste handlers
UN Number: Not regulated for most forms of transport (verify if packaging or country dictates otherwise)
Transport Hazard Class: Not classified
