Chemical Name: 2-Benzoylthiophene
CAS Number: 2134-02-1
Concentration: ≥ 97% (based on supplier specification)
Impurities: Trace amounts of related ketones and thiophene derivatives, less than 3% total impurities
Inhalation: Move individual to fresh air, support breathing as needed, seek medical help if symptoms linger
Skin Contact: Remove contaminated clothes, wash affected area thoroughly with soap and water for at least fifteen minutes, see a doctor if irritation remains
Eye Contact: Rinse eyes with water for several minutes, lift eyelids occasionally, consult physician for persistent pain or redness
Ingestion: Rinse mouth, drink water if conscious, do not try to induce vomiting, get immediate medical attention
General Advice: Show physician this sheet and any available product container for reference; watch for delayed symptoms
Suitable Extinguishing Media: Use dry chemical, foam, or carbon dioxide; avoid heavy water spray which may spread contamination
Special Hazards from Fire: Produces hazardous fumes (carbon oxides, sulfur oxides) upon burning, thick smoke possible, vapors may ignite above certain temperatures
Protective Equipment for Firefighters: Wear self-contained breathing apparatus, full protective gear
Firefighting Instructions: Keep containers cool with water spray, isolate fire site, prevent runoff from entering drains or watercourses
Personal Precautions: Wear gloves, goggles, lab coat; avoid skin contact and breathing dust
Spill Cleanup: Sweep up solid material without creating dust, place in sealed chemical waste container, ventilate area
Environmental Precautions: Prevent chemical from entering water, drains, or soil
Disposal: Collect material in suitable containers for disposal according to local, state, and federal rules
Handling: Work only in well-ventilated area or fume hood, avoid dust generation, use protective clothing, keep containers tightly closed
Hygiene Measures: Wash hands before breaks and at end of shift, do not eat, drink, or smoke around work area
Storage Conditions: Store in cool, dry, well-ventilated place, keep product away from strong oxidizers, acids, and sources of ignition, protect from moisture and sunlight
Suitable Packaging: Use non-reactive containers made from glass or high-density polyethylene, label clearly
Exposure Limits: No established occupational exposure limits known for this chemical
Engineering Controls: Local ventilation such as fume hoods recommended, safety showers and eyewash available
Personal Protective Equipment: Wear gloves (nitrile or neoprene), chemical-resistant goggles, lab coat, and, if dust is present, use a suitable respirator (P95 or above)
Environmental Controls: Minimize exposure to drains and environment, use spill containment as needed
Appearance: Off-white to pale yellow crystalline solid
Odor: Slight aromatic odor
Melting Point: Ranges from 91–95°C
Boiling Point: Not precisely determined, decomposes above 200°C
Solubility: Slightly soluble in water, more soluble in organic solvents (ethanol, dichloromethane)
Density: Approximately 1.21 g/cm³
Vapor Pressure: Low at room temperature
pH: Not applicable (solid compound)
Partition Coefficient (log Kow): Not measured, likely high based on structure
Chemical Stability: Stable under recommended handling and storage conditions
Conditions to Avoid: Strong heating, moisture, sunlight, oxidizers, acids
Incompatible Materials: Strong oxidizing agents, acids, strong bases
Hazardous Decomposition Products: Carbon monoxide, carbon dioxide, oxides of sulfur, toxic fumes
Polymerization: Not known to occur
Acute Toxicity: Harmful if swallowed, based on related compounds expected LD50 (oral, rat) above 300 mg/kg
Skin Corrosion/Irritation: Irritates skin on contact, more risk with repeated exposure
Serious Eye Damage/Irritation: Causes irritation, watery and red eyes, could cause temporary vision disturbance
Respiratory or Skin Sensitization: Prolonged contact may cause allergic skin reactions in sensitive individuals
Chronic Toxicity: Limited data, long-term effects on organs not fully studied
Carcinogenicity: No evidence from animal or human data yet, but lack of studies doesn't prove safety; sensible to handle with solid precautions as for any aromatic ketone
Mutagenicity: No specific data
Reproductive Toxicity: Not established
Ecotoxicity: Toxic to aquatic organisms based on structural similarity to related compounds, may cause long-term harmful effects in water
Persistence and Degradability: Expected to be persistent, unreactive toward hydrolysis, not easily broken down by soil bacteria
Bioaccumulation Potential: Likely to bioaccumulate due to high partition coefficient; can concentrate in aquatic life
Mobility in Soil: Low water solubility limits movement, tends to adhere to soil particles
Other Adverse Effects: Not biodegradable, avoid significant leakage into environment
Waste Treatment Methods: Use approved chemical incinerator, follow all local, regional, and national guidelines; do not dump remains down sink or toilet
Contaminated Containers: Rinse thoroughly, dispose as hazardous chemical waste; labels must remain until thoroughly cleaned
Special Precautions: Do not mix with general waste stream, keep separate from strong oxidizers during disposal
Disposal Regulations: Consult with licensed hazardous waste disposal contractor for guidance on legal burning or chemical breakdown
UN Number: Not specifically assigned, treat as hazardous lab chemical during transport
Proper Shipping Name: Laboratory chemical, solid, n.o.s. (contains 2-Benzoylthiophene)
Transport Hazard Class: Not classified as flammable, but avoid direct contact or dusty leakage
Packing Group: III (if applicable)
Marine Pollutant: Yes, based on aquatic toxicity
Special Precautions for User: Carry in secondary containment, label clearly, transport with spill kit and PPE available
OSHA Classification: Hazardous chemical
TSCA Inventory: Listed
EU REACH Status: Not registered
WHMIS Classification: D2B (toxic material causing other toxic effects)
SARA Title III: Not listed under specific sections, but treat as hazardous for emergency planning
California Proposition 65: No direct listing, but safety precautions still apply in California workplaces
