Product Name: 1-Bromo-2,4-Dinitrobenzene Chemical Formula: C6H3BrN2O4 CAS Number: 585-79-5 Synonyms: 2,4-Dinitrobromobenzene Recommended Use: Laboratory reagent, chemical synthesis Manufacturer: Chemical supplier information on label Contact Information: Phone number, emergency hotline, and address available on product container Emergency Numbers: Refer to local emergency center
Hazard Class: Acute toxicity (oral, dermal, inhalation), skin and eye irritant Pictograms: Skull and crossbones, exclamation mark GHS Signal Word: Danger Hazard Statements: Toxic if swallowed, inhaled, or in contact with skin; causes severe eye irritation and skin irritation; may cause allergic skin reaction Precautionary Statements: Avoid breathing dust, fumes, or vapors; wash thoroughly after handling; wear protective clothing, gloves, and eye protection Routes of Exposure: Inhalation, ingestion, skin, and eye contact
Chemical Identity: 1-Bromo-2,4-Dinitrobenzene Purity: >98% Impurities: Trace unreacted compounds, related nitrobenzenes Molecular Weight: 263 g/mol Other Components: No significant additives
Inhalation: Move to fresh air at once. Keep quiet and warm. Seek medical attention if coughing, shortness of breath, or other symptoms appear. Skin Contact: Remove contaminated clothing. Wash skin thoroughly with soap and plenty of water for at least 15 minutes. Get medical help for irritation or allergic reaction. Eye Contact: Rinse eyes cautiously with water for several minutes, lifting eyelids often. Remove contact lenses if present and continue rinsing. Get medical attention right away. Ingestion: Rinse mouth with plenty of water. Do not induce vomiting unless directed by medical personnel. Get medical help immediately. General Advice: Show product label or SDS to medical personnel.
Suitable Extinguishing Media: Dry chemical, foam, carbon dioxide, or water spray for small fires Unsuitable Media: Do not use direct water jet on burning chemical Special Hazards: Emits toxic fumes of nitrogen oxides, bromine compounds, and carbon oxides on combustion Protective Equipment: Firefighters should wear full protective gear and self-contained breathing apparatus Specific Methods: Move containers away from fire if safe. Cool containers exposed to heat with water spray. Contain run-off to prevent entry into waterways Fire/Explosion Risk: Non-flammable but may intensify fire due to oxidizing nature of nitro groups
Personal Protection: Use protective gloves, clothing, safety goggles, and a respirator if potential for dust exposure exists Environment Protection: Prevent spillage from reaching drains, surface water, or soil Containment: Sweep up and collect spilled material using non-sparking tools; avoid creating dust Clean-Up Methods: Place collected material in sealed containers for disposal; ventilate area thoroughly Notification: Report spills to proper authorities, especially if going outside facility
Handling: Use only in well-ventilated areas or fume hoods. Avoid breathing dust or contact with skin and eyes. Always wear appropriate PPE. Practice good hygiene after working with chemical. General Precautions: Keep away from food and drinks. Do not eat or smoke during handling. Use dedicated equipment. Storage Conditions: Store in tightly closed containers away from heat, sparks, direct sunlight, and strong acids or bases. Keep at ambient temperature in a dry, well-ventilated area. Incompatibilities: Strong reducing agents, alkali metals, and strong bases Storage Class: Toxic and hazardous substances
Exposure Limits: No official OSHA or ACGIH limits; treat as hazardous
Engineering Controls: Local exhaust ventilation, chemical fume hood
Personal Protective Equipment:
– Eyes: Safety goggles or face shield
– Skin: Chemical resistant gloves (nitrile, neoprene), lab coat
– Respiratory: Dust mask or respirator in poorly ventilated areas
– Work Practices: Wash hands after handling, do not touch face, remove contaminated clothing
Appearance: Yellow crystalline solid Odor: Mild aromatic odor Melting Point: 89–92°C Boiling Point: Not available; decomposes before boiling Solubility: Insoluble in water, soluble in ethanol and organic solvents Vapor Pressure: Negligible at room temperature Flash Point: Non-flammable Density: 1.9 g/cm³ (approximate) pH: Not applicable Partition Coefficient (Log Kow): Estimated 2.6–3 Autoignition Temperature: No data Evaporation Rate: Not applicable
Chemical Stability: Stable under ordinary conditions. Decomposes under heat, sparks, or open flames producing toxic gases Conditions to Avoid: Heat, light, sparks, open flames, strong shock, and static discharge Materials to Avoid: Strong bases, reducing agents, and incompatible chemicals that could release heat or gases Hazardous Decomposition: Nitrogen oxides, bromine fumes, carbon oxides Hazardous Polymerization: Not expected
Acute Toxicity: Harmful by inhalation, ingestion, or skin contact; LD50 (oral, rat): 200–500 mg/kg (estimate based on structure) Chronic Effects: Prolonged exposure may cause organ damage, especially liver and kidneys Carcinogenicity: Not evaluated by IARC, NTP, or OSHA Mutagenicity: No reliable data, but nitroaromatic compounds often carry risk Sensitization: Can cause allergic skin reactions Routes of Entry: Skin, eyes, inhalation, ingestion Symptoms: Irritation, dizziness, headache, nausea, weakness, red or itchy skin
Aquatic Toxicity: Harmful to aquatic organisms; long-term adverse effects possible Mobility: Low in water systems due to low solubility Persistence and Degradability: Likely to persist in the environment; slow biodegradation Bioaccumulation: Potential for bioaccumulation based on structure Other Effects: Toxic to fish and invertebrates if released in large quantities
Waste Treatment Methods: Dispose as hazardous waste following local, state, and federal regulations Incineration: Approved chemical incinerator with afterburner and scrubber Container Disposal: Triple rinse, puncture, and dispose in hazardous waste landfill Precautions: Do not allow substance or runoff into drains, soil, or natural waterways Transportation: Use sealed, labeled containers for waste
UN Number: 2811 Proper Shipping Name: Toxic solid, organic, n.o.s. (1-Bromo-2,4-Dinitrobenzene) Transport Hazard Class: 6.1 (Toxic substances) Packing Group: III Label Required: Toxic, environmental hazard Other Requirements: Keep away from incompatible substances, protected from moisture and heat during transit
TSCA: Listed on Toxic Substances Control Act REACH: Substance subject to registration in the EU OSHA Hazard: Classified as hazardous SARA 313: Not listed DSL (Canada): Present WHMIS Classification: D1B (Toxic), D2B (Other Toxic Effects) Other National/Inernational Regulations: Users should refer to national chemical safety regulations and workplace safety rules applicable to hazardous chemicals
