Impurities: Trace levels of related phenazine compounds may occur due to synthesis routes
Stabilizers/Trade Secret Additives: None identified in typical laboratory or manufacturing grades
Inhalation: Move person to fresh air, keep at rest in a position comfortable for breathing, seek medical advice if symptoms like cough or dizziness show up
Skin Contact: Remove contaminated clothing immediately, rinse well with plenty of water and soap, seek medical attention for persistent irritation or rash
Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses if present and easy, keep rinsing, get prompt medical help for any vision change or lasting pain
Ingestion: Rinse mouth, do not induce vomiting, give water if person is conscious, get immediate medical advice and show this sheet to caregivers
Suitable Extinguishing Media: Water spray, dry chemical powder, carbon dioxide, or foam
Unsuitable Extinguishing Media: Avoid direct water jet, which may cause chemical splatter
Specific Hazards: Containers may rupture under fire conditions, toxic gases like nitrogen oxides may come off
Protective Equipment for Firefighters: Full protective clothing and self-contained breathing apparatus, avoid inhaling fumes, evacuate area if safe containment is not possible
Personal Precautions: Ventilate area, keep unnecessary people away, put on gloves, chemical splash goggles, dust mask if needed
Environmental Precautions: Prevent entry to drains, surface water, and soil, report significant spills to environmental authorities
Cleanup Methods: Collect dry powder using non-sparking tools, place in suitable container for waste disposal, wash spill area with water and detergent, avoid raising dust during cleanup
Handling: Work in fume hood or ventilated space, avoid breathing dust or fumes, keep containers tightly closed during use, wash hands thoroughly after handling, keep away from food and drink
Storage Conditions: Store in cool, dry, and well-ventilated area, keep away from open flames or sources of static discharge, avoid direct sunlight, use tightly sealed containers to prevent moisture and air exposure, label storage shelves clearly, monitor for container integrity
Exposure Limits: Not established by OSHA, NIOSH, or ACGIH for this compound, use general workplace hygiene limits for nuisance dust (e.g., 10 mg/m³) as a guide
Engineering Controls: Use laboratory fume hood or local exhaust ventilation for bulk handling
Personal Protective Equipment: Chemical-resistant gloves (nitrile or neoprene), splash goggles, lab coat or chemical apron, dust mask or respirator with P100 cartridge for powder handling, safety boots in case of large-scale work
Hygiene Measures: No eating, drinking, or smoking during handling, wash before breaks and after shift, clean work surfaces regularly
Appearance: Yellow to brown crystalline powder
Odor: Slight, chemical-like
Molecular Weight: 210.24 g/mol
Melting Point: 236-238°C
Boiling Point: Not available, decomposition may occur before boiling
Solubility: Slightly soluble in water, more soluble in alcohol or organic solvents
Vapor Pressure: Not available
Density: Around 1.36 g/cm³
pH: Not applicable for solid
Chemical Stability: Stable under recommended storage and handling conditions
Reactivity: No hazardous reactivity under normal use
Conditions to Avoid: Strong heat, fire, contact with strong oxidizing agents or acids
Hazardous Decomposition Products: Nitrogen oxides, toxic aromatic compounds may form in fire situation
Incompatible Materials: Powerful oxidizers, acidic or alkaline solutions may increase risk of hazardous reactions
Acute Toxicity: Harmful if swallowed, oral LD50 (rat) estimated at 300-2000 mg/kg
Skin Corrosion/Irritation: May cause skin redness and swelling in sensitive individuals
Serious Eye Damage/Irritation: Temporary irritation possible, redness, watering
Respiratory or Skin Sensitization: Possible allergic reactions with repeated or prolonged contact
Mutagenicity/Carcinogenicity: No long-term studies available, cautious approach recommended due to chemical structure similarity to some dye intermediates
Other Effects: No data on reproductive toxicity; chronic health risks uncertain due to rare use
Ecotoxicity: Data sparse, structurally-related compounds show moderate aquatic toxicity
Persistence and Degradability: Likely low biodegradability, compound may persist in soil or water
Bioaccumulative Potential: Calculated log Kow suggests possible accumulation in aquatic species
Mobility in Soil: Limited water solubility suggests low mobility, risk of localized impacts at spill sites
Other Adverse Effects: No evidence of ozone depletion or photochemical smog properties, hazard mainly comes from direct water contamination
Waste Disposal Methods: Collect and label waste, send to licensed chemical waste incinerator, avoid landfill or sewer by any route
Container Disposal: Triple rinse containers before disposal, mark as hazardous if traces remain, follow local, regional, and national waste guidelines
Contaminated Packaging: Treat as chemical waste, remove usable labels, prevent re-use for food or water storage
