Chemical Name: 2,2-Dibromo-3-Nitrilopropionamide
CAS Number: 10222-01-2
Concentration: 98-100% by weight
Impurities: May include trace organic/inorganic residues from synthesis—consult certificate of analysis for batch-specific information
Inhalation: Move affected person to fresh air at once. Call emergency services. If signs of distress appear—shortness of breath, cough, nausea—doctor needs to assess immediately.
Skin Contact: Remove contaminated clothing and wash skin with plenty of flowing water and soap for at least 20 minutes. Do not scrub. Get prompt medical attention.
Eye Contact: Rinse eyes slowly and gently with water for no less than 20 minutes. Keep eyelids open. Get medical care quickly, even if symptoms seem minor.
Ingestion: If swallowed, do not induce vomiting. Rinse mouth thoroughly. Get urgent medical attention. Show the container or label wherever possible.
Major Symptoms: Skin blistering, respiratory irritation, eye burns, headaches, nausea, abdominal pain, severe allergic reactions
Suitable Extinguishing Media: Dry chemical, foam, CO₂ for small fires; water spray or regular foam for larger fires
Unsuitable Extinguishing Media: Do not use water jet directly—may spread chemicals
Special Hazards: Releases toxic fumes including hydrogen bromide, oxides of nitrogen, and cyanide compounds in a fire
Protective Equipment: Full protective fire gear, self-contained breathing apparatus required for exposure in smoky or toxic atmospheres
Firefighting Guidance: Move containers from fire area if safe, avoid runoff into water supplies, ventilate area post-extinguishment
Personal Protection: Use chemical splash goggles, nitrile gloves, long sleeves, chemical resistant apron, and a respirator for dust or vapor
Environmental Precautions: Prevent entry into drains, sewers, waterways; notify authorities if significant contamination threatens a watercourse; dike and contain spill
Cleanup Methods: Use inert absorbents (sand, earth). Collect in sealed, labeled containers using non-sparking tools. Wash contaminated surfaces with lots of water.
Disposal: Place all contaminated materials in approved hazardous waste containers for safe disposal
Handling: Avoid contact with skin, mucous membranes, and eyes. Only use in well-ventilated environments. Do not breathe dust. Handle away from incompatible materials such as strong oxidizers, reducing agents, or bases.
Storage: Store in tightly closed original containers or approved chemical drums, out of direct sunlight, in a dry, cool, well-ventilated area inaccessible to unauthorized workers or children.
Storage Temperature: Safeguard from extreme temperatures. Recommended range sits between 5°C and 25°C; keep away from heat sources.
Incompatibles: Avoid mixing with acids, alkalis, oxidizers, or moisture to reduce decomposition and emission of hazardous byproducts.
Exposure Limits: No established occupational exposure limits for DBNPA (check local/national guidelines for updates)
Engineering Controls: Local exhaust ventilation recommended for routine handling, supplemented with general dilution ventilation where necessary
Personal Protective Equipment: NIOSH/OSHA-approved respirator in case of inadequate ventilation, splash goggles, full-length chemical resistant gloves, face shield during possible splashing, flame-retardant lab coat
Hygiene Measures: Wash hands thoroughly before breaks, after handling; do not eat/drink/smoke in workspace where chemical is used
Appearance: White to off-white crystalline powder
Odor: Slight chemical aroma
pH: Acidic (5% solution lies between pH 4 and 6)
Melting Point: 125–127°C
Boiling Point: Decomposes before boiling
Flash Point: Non-flammable under normal conditions
Solubility: Soluble in water, alcohols, and some organic solvents
Vapor Pressure: Extremely low under ambient conditions
Relative Density: About 2.1 (water = 1)
Partition Coefficient (n-octanol/water): Data available on request—moderately mobile
Stability in Storage: Stable if kept dry and sealed
Chemical Stability: Stable in dry, sealed conditions; rapidly loses efficacy in presence of strong acids/bases, reducing agents
Decomposition Products: Hydrogen bromide gas, oxides of nitrogen, cyanide-type fumes if combusted
Polymerization: No risk of hazardous polymerization reported with normal use
Incompatibility: Incompatible with strong oxidizers, bases, reducing agents, certain metals
Conditions to Avoid: Excessive heat, open flame, humidity, unapproved chemical reactions or admixture
Routes of Exposure: Inhalation, ingestion, skin and eye contact
Acute Toxicity: LD50 (oral, rat): 125 mg/kg; LD50 (dermal, rabbit): ~800 mg/kg
Symptoms: Nausea, burns, coughing, difficulty breathing, headache, possible delayed respiratory distress
Chronic Toxicity: Evidence points to severe skin sensitization, chronic respiratory irritation with frequent exposure. Carcinogenicity not classified by IARC, NTP, or OSHA but still warrants careful attention.
Other Data: May produce allergic reactions in previously sensitized individuals. No reproductive toxicity seen in limited animal studies.
Ecotoxicity: DBNPA is toxic to aquatic organisms, particularly fish, invertebrates, and algae, with LC50s below 1 mg/L in multiple standard tests
Persistence and Degradability: Rapid hydrolysis in water—half-life dives under typical environmental conditions; forms less toxic byproducts
Bioaccumulation: No significant bioaccumulation reported
Mobility: Moderately mobile in groundwater but mostly breaks down before reaching significant distance
Notes: Use near open waterways needs careful handling. Notify local environmental authorities if accidental release exceeds regulation limits.
Waste Treatment Methods: Incineration or high temperature chemical destruction in registered hazardous waste facilities for both product and contaminated packaging
Contaminated Packaging: Rinse thoroughly. Dispose of as hazardous waste according to local and national regulations for environmental protection
Precautions: Do not discharge into sewage, stormwater, or natural water bodies
