Impurities: Trace levels possible – phenyl derivatives, pyridines, solvents or water from synthesis
General Advice: Remove victim from exposure area to fresh air immediately, seek medical attention for any persistent symptoms
Inhalation: Move to fresh air, keep at rest, consult doctor if symptoms persist such as coughing or throat irritation
Skin Contact: Wash thoroughly with soap and water, remove contaminated clothing, see physician if irritation develops
Eye Contact: Rinse cautiously with water for at least 15 minutes, remove contact lenses if present, medical help required if irritation does not subside
Ingestion: Rinse mouth with water, do not induce vomiting, seek immediate medical attention
Suitable Extinguishing Media: Foam, dry chemical, carbon dioxide, or water spray
Unsuitable Extinguishing Media: Direct water jet on burning chemical powder can spread fire
Specific Hazards: Combustion may give rise to toxic fumes including carbon oxides and nitrogen oxides
Protective Equipment: Firefighters use self-contained breathing apparatus, chemical-resistant suit
Recommendations: Move containers from fire area if safe, cool with water spray, prevent run-off from entering drains or waterways
Personal Precautions: Evacuate unprotected personnel, wear appropriate personal protective equipment
Environmental Precautions: Prevent entry into drains, surface water, or soil
Cleanup Methods: Absorb spills with inert material, sweep up, place in appropriate waste container; ventilate area, decontaminate tools and equipment
Additional Notes: Large spills require containment by diking and notification to regulatory bodies if risk of wider contamination
Handling: Avoid breathing dust, handle under exhaust ventilation, always wear gloves and goggles while weighing and mixing
Hygiene Practices: Wash hands after use, clean work area after handling, avoid eating or drinking nearby
Storage Conditions: Keep container tightly closed in dry, well-ventilated place, away from incompatible materials such as oxidizing agents
Container Materials: Use glass, high-quality plastic or safety-sealed metal drums; check for chemical compatibility
Special Considerations: Store away from ignition sources, sunlight, and out of reach of inexperienced handlers
Control Parameters: Occupational exposure limits not established directly for this compound, minimize exposure using engineering controls
Engineering Controls: Fume hood or local exhaust recommended
Personal Protective Equipment: Splash goggles, chemical-resistant gloves (nitrile, PVC), lab coat
Respiratory Protection: Dust mask or respirator recommended for dusty operations or where ventilation is insufficient
Hygiene Measures: Eye wash stations, emergency showers in the working area
Appearance: White to pale yellow crystalline powder
Odor: Mild aromatic
Melting Point: 54 - 57°C
Boiling Point: 337°C (estimated)
Solubility: Slightly soluble in water, soluble in organic solvents such as acetone, ethanol, and chloroform
Density: 1.152 g/cm³ (at 20°C)
Flash Point: > 150°C (closed cup)
Vapor Pressure: Rather low at ambient temperatures
pH: Not applicable (neutral in nature)
Partition Coefficient: logP (octanol/water) about 2.5 - 3 (estimated)
Chemical Stability: Stable in closed containers under recommended handling and storage conditions
Reactivity: May react with strong oxidizers, acids, and bases
Conditions to Avoid: Direct sunlight, heat, moisture, open flames
Decomposition Products: Burning produces carbon monoxide, carbon dioxide, nitrogen oxides
Polymerization: No hazardous polymerization expected under normal process
Route of Exposure: Inhalation, ingestion, skin absorption possible
Acute Toxicity: Data limited, but structurally related pyrrole compounds may pose toxicity at higher doses, irritation common
Symptoms: Eye, skin, and respiratory irritation; cough, redness, possible headache or allergic skin reactions
Long-term Exposure: Chronic effects not well documented in humans; animal tests suggest low organ toxicity at moderate exposure with some pyrroles
Carcinogenicity: No information on cancer risk in humans
Other Effects: May aggravate existing dermatitis or asthma
Ecotoxicity: Data lacking, but structurally similar pyrroles indicate low to moderate toxicity to aquatic species
Persistence and Degradability: Likely not readily biodegradable in environment, potential for slow breakdown
Bioaccumulation: Potential for accumulation in aquatic life forms cannot be ruled out
Mobility: Limited water solubility translates to moderate migration in soil
Other Information: Avoid uncontrolled release to environment, contain run-off and minimize waste
Waste Disposal Methods: Treat as hazardous chemical waste, contact licensed chemical disposal service
Container Disposal: Triple rinse, dispose in accord with local and national regulations for hazardous containers
Special Instructions: Do not release to drains, waterways, or environment; incineration in approved facility preferred
