Chemical Name: Sulfachloropyrazine Sodium
Percentage by Weight: >95% active ingredient
Impurities: Sodium chloride, process-related residuals, trace of unreacted sulfonamide derivatives
Other Components: Not considered hazardous under current regulatory criteria
Inhalation: Move person to fresh air, keep at rest in comfortable position, seek medical attention for coughing or breathing difficulty
Skin Contact: Remove contaminated clothing, wash affected skin area with soap and water for at least 20 minutes, seek medical advice if irritation persists
Eye Contact: Immediately flush eyes with plenty of running water for 15 minutes, lifting upper and lower lids occasionally, remove contact lenses if present
Ingestion: Rinse mouth with water, do not induce vomiting unless directed by medical personnel, seek immediate medical evaluation
Advice to Physicians: Treat symptomatically, monitor for allergic or hypersensitivity reactions, administer supportive care if required
Suitable Extinguishing Media: Dry chemical, carbon dioxide, foam, water spray
Unsuitable Media: Strong water streams may cause contamination spread
Hazardous Combustion Products: Emits toxic fumes of nitrogen oxides, sulfur oxides, hydrochloric acid, and sodium oxides during combustion
Protective Equipment: Firefighters need self-contained breathing apparatus and protective clothing
Special Procedures: Cool surrounding containers with water, prevent runoff from entering drains or water sources, evacuate area if necessary due to toxic gases
Personal Precautions: Wear NIOSH-approved respirator, chemical-resistant gloves, eye protection, minimize dust generation
Environmental Precautions: Prevent powder from entering watercourses or drains, avoid contaminating soil, report large releases to local authorities
Methods for Cleanup: Carefully sweep up spilled material without creating dust, place in appropriate waste disposal container for collection, rinse area with water and detergent, ventilate affected area after cleanup
Handling: Avoid inhaling dust or direct contact with skin and eyes, use only with adequate ventilation, handle with care to keep container tightly closed
Storage Requirements: Store in tightly sealed original containers, cool dry well-ventilated place, away from incompatible substances such as acids and oxidizing agents
Specific Storage Details: Protect from moisture and direct sunlight, keep out of reach of children and animals, avoid excessive stacking to prevent container breakage
Exposure Limits: No official occupational exposure limits set by OSHA or ACGIH
Engineering Controls: Use local exhaust ventilation where dust may be generated, maintain positive airflow to limit accumulation
Personal Protective Equipment: Wear chemical-resistant gloves (nitrile or neoprene), safety goggles, protective clothing (lab coat or coveralls), NIOSH/MSHA approved respirator if exposure limits exceeded or dust present
Additional Precautions: No eating or drinking in work areas; always wash hands thoroughly after handling
Appearance: White to pale yellow powder or granules
Odor: Faint, unremarkable odor
pH (1% Solution): Around 8–10
Melting Point: Decomposes above 250°C
Solubility: Freely soluble in water
Relative Density: About 1.55 g/cm³
Partition Coefficient (log Kow): Not significantly lipophilic, low to moderate mobility in the environment
Vapor Pressure: Negligible at room temperature
Boiling Point: Not applicable (decomposes before boiling)
Flash Point: Not flammable
Chemical Stability: Stable under normal conditions of storage and use, decomposes with prolonged heat or exposure to strong sunlight
Conditions to Avoid: High temperature, moisture, exposure to strong oxidizing agents and acids
Incompatible Materials: Strong oxidizers, acids, bases
Hazardous Decomposition Products: Toxic fumes including nitrogen oxides, sulfur oxides, sodium oxides, possible trace chlorine compounds
Polymerization: No risk of hazardous polymerization
Routes of Exposure: Inhalation, ingestion, skin and eye contact
Acute Toxicity: LD50 (oral, rat): 3,000–5,000 mg/kg; may cause gastrointestinal upset, nausea, vomiting, diarrhea
Skin Sensitization: Evidence of allergy or dermatitis with repeated/prolonged contact
Eye Effects: Irritation, redness, pain with direct contact
Chronic Effects: Prolonged exposure can impact blood parameters, minor effects seen in animal reproduction studies, not classified conclusively as a carcinogen
Other Data: No evidence of mutagenicity or carcinogenicity in standard animal bioassays, not proven teratogenic, possible idiosyncratic drug reactions in some humans
Ecotoxicity: Moderate toxicity to aquatic invertebrates and fish, EC50 (Daphnia magna): 12–30 mg/L over 48 hours
Persistence and Degradability: Degrades slowly under natural conditions, moderate bioaccumulation risk
Mobility in Soil: Leachable in water-saturated soils due to high water solubility, binds weakly to organic matter
Other Environmental Hazards: Harmful to aquatic life with long lasting effects, risk for secondary poisoning in non-target organisms through food chain
Precaution: Avoid application near waterways, observe local guidelines regarding veterinary pharmaceutical residues
Waste Disposal Methods: Dispose as hazardous pharmaceutical waste through authorized contractor, incinerate in licensed facility, comply with local legislation
Container Disposal: Triple rinse and offer for recycling or puncture and dispose in approved landfill (do not reuse containers for other purposes)
