Impurities: Trace residual solvents from synthesis possible in analytical grades
Inhalation: Move affected person to fresh air immediately; seek medical attention if breathing becomes difficult
Skin Contact: Wash exposed skin with soap and plenty of water; remove contaminated clothing
Eye Contact: Rinse eyes thoroughly with clean water for at least 15 minutes; obtain medical advice if discomfort persists
Ingestion: Rinse mouth with water; do not induce vomiting; call a poison center or healthcare provider
Special Notes: Always report sustained exposures or symptoms of discomfort to a healthcare provider
Suitable Extinguishing Media: Dry chemical powder, carbon dioxide, foam; do not use water jets
Specific Hazards: Emits toxic fumes of phosphorus oxides and iodine compounds on burning
Special Protective Equipment: Firefighters wear self-contained breathing apparatus and full protective gear
Advice for Firefighters: Entrenched fires may need evacuation of area; keep containers cool with water spray away from leaking surfaces
Personal Precautions: Wear laboratory gloves, goggles, and a dust mask
Environmental Precautions: Prevent large-scale spills from reaching drains and watercourses
Cleanup Methods: Scoop up solids in disposable, chemically resistant containers, ventilate the area, wash residues from surfaces with water and detergent
Disposal: Transfer all material and cleanup waste into labeled waste disposal containers for routine laboratory hazardous waste pickup
Safe Handling Practices: Use only in well-ventilated laboratory settings; avoid inhaling dust or direct contact with eyes and skin
Recommendations: Handle with gloves and eye protection, keep material in tightly sealed containers
Storage Conditions: Store in cool, dry, well-ventilated, secure cabinets away from incompatible substances like strong oxidizers
Packaging: Keep original containers tightly closed and clearly labeled
Exposure Limits: No specific national exposure limits established for this material
Engineering Controls: Work with fume hoods or local exhaust ventilation if dust formation possible
Personal Protection: Use splash-resistant safety goggles, chemical-resistant gloves (nitrile, latex), standard lab coats
Respiratory Protection: Dust mask or respirator if ventilation insufficient
Hygiene Measures: Wash hands thoroughly before breaks and after handling
Appearance: White or off-white crystalline powder
Odor: Odorless
Melting Point: 250°C – 255°C (decomposes)
Boiling Point: Not applicable
Solubility: Moderately soluble in water and organic solvents like dimethyl sulfoxide
Vapor Pressure: Not measurable
Density: Around 1.51 g/cm³
pH: Not measurable in neutral solutions
Flash Point: Not flammable under normal laboratory conditions
Chemical Stability: Stable under normal laboratory conditions with proper storage
Conditions to Avoid: High temperature, direct sunlight, exposure to strong oxidizers and acids
Incompatible Materials: Strong oxidizing agents; strong acids
Hazardous Decomposition: Heating or burning produces toxic fumes of phosphorus oxides and iodine compounds
Polymerization: No hazardous polymerization tendency
Likely Routes of Exposure: Inhalation, skin, and eye contact
Acute Symptoms: Mild irritation possible in cases of direct contact; inhalation of dust causes respiratory tract irritation
Chronic Exposure: Data lacking for chronic toxicity in humans; keep exposures as low as possible
Carcinogenicity: Not classified as a known carcinogen
Mutagenicity: No reliable evidence for mutagenic effects
Reproductive Toxicity: No studies indicating reproductive toxicity
Eco-Toxicity: Information limited, but anticipated low acute aquatic toxicity based on structure
Persistence and Degradability: Degradation in environment not rapid; risk of bioaccumulation low
Bioaccumulative Potential: Structure suggests low potential for accumulation in aquatic organisms
Mobility in Soil: Likely to adsorb to soils given ionic nature of salt
Other Adverse Effects: Minimize release to environment; practice good laboratory drain disposal policy for small volumes
Product Disposal: Hand over materials to appropriate hazardous waste disposal specialists
Contaminated Packaging: Handle as hazardous laboratory waste; do not reuse containers
Disposal Methods: Chemical waste incineration or approved hazardous landfill in compliance with local statutes and regulations
Regulatory Compliance: Refer to institutional and local hazardous waste guidelines; do not discharge to sewer or surface water
