Eye Contact: Rinse thoroughly with plenty of clean water for at least 15 minutes, remove contact lenses if present, seek medical help if irritation persists.
Skin Contact: Remove contaminated clothing, wash affected area with soap and water, medical support if redness or irritation develops.
Inhalation: Move to fresh air promptly, rest if difficulties develop, seek medical attention if symptoms continue.
Ingestion: Rinse mouth, do not induce vomiting without consultation, consult a physician right away.
Special Notes: Symptomatic treatment needed; medical staff to treat per exposure and symptoms.
Suitable Extinguishing Media: Dry chemical, foam, carbon dioxide, or water spray for cooling containers and surroundings.
Unsuitable Extinguishing Media: Direct water jet may spread chemical.
Fire Hazards: Product may decompose under fire conditions to release toxic fumes of iodine and nitrogen compounds.
Special Protective Equipment: Self-contained breathing apparatus and full protective gear required, as combustion gases can irritate respiratory tract.
Firefighting Instructions: Use water spray for cooling, avoid runoff entering sewers, remain upwind to avoid vapor inhalation.
Personal Precautions: Don chemical-resistant gloves, safety goggles, and protective clothing before starting cleanup, ventilate area, avoid breathing vapors.
Environmental Precautions: Prevent chemical from entering soil, drains, and water bodies; possible high aquatic toxicity.
Cleanup Procedures: Absorb spill using inert material (such as sand or vermiculite), collect for proper waste disposal, rinse area with large amounts of water.
Handling: Avoid contact with skin, eyes, and clothing; keep container tightly closed when not in use; operate in well-ventilated facility with accessible safety equipment including eyewash stations.
Storage: Store at ambient temperature in dry, cool, and well-ventilated area; keep containers securely sealed, away from incompatible materials like strong oxidizers and moisture sources.
Special Notes: Clearly label all storage and working containers, restrict access to personnel trained in chemical safety.
Exposure Limits: No established occupational exposure limits for this compound; treat with caution in the absence of toxicity data.
Engineering Controls: Use enclosures or local exhaust ventilation to minimize exposure; maintain good general ventilation.
Personal Protective Equipment: Chemical-resistant gloves (nitrile suggested), safety goggles, lab coat, if necessary, face shield and respirator (NIOSH/EN 143 standard or equivalent) for handling dusts or large volumes.
Hygiene Measures: Wash hands and exposed skin thoroughly after handling; change contaminated clothing immediately.
Appearance: Off-white to pale yellow crystalline powder or viscous liquid, depending on purity and temperature.
Odor: Faint, may have mild iodine-like or aromatic scent.
Melting Point: Reported around 90–110°C; varies by sample purity.
Boiling Point: Decomposes before boiling.
Solubility: Soluble in water and polar organic solvents.
Vapor Pressure: Very low under ambient conditions.
Density: Approximately 1.2–1.3 g/cm³.
pH: No strong acid/alkaline tendency in neutral water solution.
Other Data: Hygroscopic, can absorb moisture from air.
Chemical Stability: Stable under recommended handling and storage; sensitive to high temperatures, strong light, and oxidizing agents.
Hazardous Reactions: Contact with powerful oxidizers results in potential hazardous product formation.
Decomposition: Elevated temperatures or fire releases iodine vapors, nitrogen oxides, and possibly corrosive imidazole fragments.
Incompatibles: Avoid oxidizing chemicals, acids or bases, and strong reducing agents.
Routes of Exposure: Skin, eyes, inhalation, ingestion.
Acute Effects: Local skin and mucous membrane irritation; ingestion and inhalation can trigger headache, nausea, and abdominal symptoms.
Chronic Effects: No well-documented chronic toxicity, but prolonged or repeated exposure may increase irritation or sensitivity.
Target Organs: Eyes, skin, respiratory and digestive tract.
Carcinogenicity, Mutagenicity, Reproductive Toxicity: No available data indicating significant risk, long-term studies lacking.
Aquatic Toxicity: Demonstrates substantial toxicity to aquatic organisms, even at low concentrations.
Persistence and Degradability: Limited biodegradation data, likely persists in the environment over extended periods.
Bioaccumulation Potential: Low to moderate, exists a risk for buildup in aquatic environments.
Mobility in Soil: Water-soluble, mobile beneath surface layers when uncontrolled spills occur.
Other Hazards: Spillage or improper disposal raises local environmental risks.
Waste Description: Unused material, spills, and contaminated cleanup residue require chemical waste classification.
Disposal Methods: Transfer to properly labeled chemical waste containers for incineration or treatment in authorized hazardous waste processing facility; never pour down drain or regular trash.
Contaminated Packaging: Rinse empty containers with suitable solvent, add rinsate to waste, and process packaging as hazardous waste.
Regulations: Comply with local, regional, and national waste management rules.
UN Number: Not specifically assigned under GHS or UN transport codes; transport as “Chemicals, N.O.S.” unless otherwise determined.
Shipping Name: Chemical under research-use restrictions.
Hazards During Transport: Avoid moisture, high heat, and mixing with incompatible products; secure containers against breakage.
