Purity: ≥ 98%
Impurities: Minute traces of related thiophene compounds, solvent residues under 1%
Mixtures: Not a mixture, single-component substance
Inhalation: Move affected person to fresh air immediately. Seek medical advice if symptoms like dizziness, coughing, headache develop.
Skin Contact: Remove contaminated clothing, rinse skin thoroughly with soap and water, seek medical advice if irritation persists.
Eye Contact: Flush eyes with plenty of water for at least 15 minutes, hold eyelids apart throughout; seek immediate ophthalmological attention.
Ingestion: Rinse mouth, avoid inducing vomiting, seek immediate medical attention.
Most important symptoms/effects: Irritation, redness, difficulty breathing or swallowing due to respiratory tract involvement, tearing or blurred vision upon eye contact.
Advice for physician: Symptomatic treatment, ensure airway and breathing, monitor for delayed effects.
Suitable Extinguishing Media: Dry chemical, carbon dioxide, foam, alcohol-resistant foam
Unsuitable Extinguishing Media: Direct water streams can spread fire
Specific Hazards: Vapors may form explosive mixtures with air; combustion produces toxic fumes such as hydrobromic acid, sulfur oxides, carbon oxides
Protective Equipment: Full fire-fighting gear and self-contained breathing apparatus
Special Procedures: Cool containers with water spray from a safe distance, prevent firewater from entering drains or waterways
Personal Precautions: Evacuate area, ventilate location, keep away from all sources of ignition.
Protective Equipment: Chemical-resistant gloves, safety goggles, laboratory coat, face shield for large spills
Environmental Precautions: Avoid discharge into drains, surface water, and soil
Methods for Cleanup: Absorb with inert material such as sand or vermiculite; collect in sealed containers for disposal; wash spill area with water
Reference to Other Sections: Refer to exposure controls, disposal considerations
Handling: Work under fume hood, avoid inhalation of fumes and contact with skin or eyes; ground containers when transferring product
Storage: Store in cool, dry, well-ventilated place away from ignition sources, direct sunlight, oxidizing agents
Container Requirements: Use tightly sealed, properly labeled containers made of compatible material (glass or HDPE)
Incompatibilities: Strong oxidizers, strong bases
Other Precautions: Use proper grounding/bonding procedures to prevent static discharge; keep away from foodstuff and drinks
Exposure Limits: No ACGIH, OSHA, or NIOSH exposure limits defined; handle as a hazardous chemical
Engineering Controls: Use local exhaust ventilation, chemical fume hood

Materials to Avoid: Strong oxidizers, alkalis, peroxides
Hazardous Decomposition Products: Hydrogen bromide, bromine, sulfur dioxide, carbon monoxide, carbon dioxide
Likely Routes of Exposure: Inhalation, skin contact, eye contact, ingestion
Acute Toxicity: No specific data; based on structural analogues, likely harmful if inhaled, ingested, or absorbed through skin
Skin Corrosion/Irritation: Expected to irritate based on related thiophenes
Eye Damage/Irritation: Likely to cause significant irritation, potential for corneal injury
Respiratory Sensitization: Vapors may cause respiratory irritation or central nervous system effects
Chronic Effects: Long-term data not available, handle with care
Carcinogenicity/Mutagenicity/Reproductive Toxicity: No evidence based on available data, no IARC/NTP/OSHA listing
Additional Hazards: Prolonged exposure may aggravate existing respiratory conditions
Ecotoxicity: No specific data available; expected to be moderately hazardous to aquatic life based on structural class
Persistence and Degradability: Slow to degrade in the environment, may persist in soil and water
Bioaccumulative Potential: Potential for bioaccumulation exists due to hydrophobic nature
Mobility in Soil: Moderately mobile, may leach to groundwater if released
Other Adverse Effects: Avoid release to environment, toxicity to fish and invertebrates cannot be ruled out
Waste Treatment Methods: Collect and contain; dispose of as hazardous waste in accordance with local, state, and federal regulations
