Other Components: No significant non-hazardous ingredients listed
Inhalation: Move affected person to fresh air immediately; loosen tight clothing; call for medical help if symptoms persist such as coughing or shortness of breath.
Skin Contact: Remove contaminated clothing; wash skin with soap and running water for at least 15 minutes; seek medical attention for irritation or burns.
Eye Contact: Rinse eyes with water, holding eyelids open for at least 15 minutes; ask for medical care especially if irritation lingers.
Ingestion: Rinse mouth with water, do not induce vomiting, consult a doctor or poison control center swiftly.
General Advice: Emergency shower and eyewash facilities should be nearby in case of accidents.
Suitable Extinguishing Media: Water spray, alcohol-resistant foam, dry chemical powder, carbon dioxide
Unsuitable Extinguishing Media: Strong water jets can spread the chemical
Specific Hazards: Combustion produces nitrogen oxides and possibly carbon monoxide
Protective Equipment: Firefighters need self-contained breathing apparatus and full protective clothing
Firefighting Advice: Approach from upwind, isolate area, prevent water runoff into sewers and waterways
Combustion Products: Toxic gases, including ammonia, may drift away from the fire scene
Personal Precautions: Wear chemical splash goggles, gloves, long sleeves, and a dust respirator
Environmental Precautions: Prevent material from reaching drains, soil, and natural waters by using containment
Clean-Up Method: Sweep or scoop spilled powder carefully into clearly labeled waste containers; ventilate spill area
Decontamination: Wash area with soapy water and wipe down surfaces thoroughly
Disposal: Treat as hazardous chemical waste; consult local regulations for hazardous waste pickup and transport
Handling: Handle inside fume hood using nitrile gloves and goggles to keep exposure down; keep containers tightly shut when not in use; avoid breathing dust or getting it on skin or clothes; do not eat, drink, or smoke in the work area
Storage: Store in a cool, dry, ventilated place away from strong oxidizers, acids, and direct sunlight; use a tightly closed amber glass container; label containers clearly
Incompatibles: Keep well back from strong oxidizing or reducing agents
Occupational Exposure Limits: Not established for Phenazine-2,3-Diamine; use general nuisance dust limits (e.g., OSHA PEL for particulates: 15 mg/m³ total dust)
Engineering Controls: Use local exhaust ventilation or work in fume hood to hold airborne dust or vapor below recommended limits
Personal Protective Equipment: Safety glasses or splash goggles, lab coat, chemical-resistant gloves, and particle-filtering respirator if dust may be present
Hygiene Measures: Wash hands and face after use; do not mix with food or drink; remove contaminated clothing before entering eating areas
Appearance: Yellow-orange crystalline powder

pH (aqueous slurry): Data not available
Melting Point: 320–324°C (dec.)
Boiling Point: Not applicable (decomposes before boiling)
Flash Point: Not available
Evaporation Rate: Not determined
Flammability: Not highly flammable but may ignite at high temperatures
Vapor Pressure: Negligible at ambient temp
Vapor Density: Not available
Solubility: Slightly soluble in water; more soluble in organic solvents like DMF or DMSO

Molecular Formula: C12H10N4
Formula Weight: 210.24 g/mol
Chemical Stability: Stable at room temperature in closed containers
Conditions to Avoid: High heat, open flames, moisture, incompatible chemicals like strong acids or oxidizers
Incompatible Materials: Potent oxidizing agents, strong acids, strong reducing agents
Decomposition Products: Toxic gases including nitrogen oxides, carbon oxides, ammonia
Hazardous Polymerization: No known polymerization hazard under normal lab conditions
Acute Toxicity: Oral LD50 (rat): data not widely available, estimated moderate toxicity; data on inhalation and dermal routes limited; may cause temporary respiratory and gastrointestinal distress
Skin Corrosion/Irritation: Causes irritation and may lead to mild dermatitis
Serious Eye Damage/Irritation: Causes burning, redness, watering
Respiratory or Skin Sensitization: Potential for allergic reactions after prolonged contact
Germ Cell Mutagenicity: Not classified
Carcinogenicity: No IARC, NTP, or OSHA listing as a confirmed carcinogen
Reproductive Toxicity: No specific data
Target Organs: Eyes, skin, respiratory system
Ecotoxicity: Little is known about environmental effects; structurally related compounds can show moderate toxicity toward aquatic organisms
Persistence and Degradability: Likely persistent due to aromatic ring structure; slow breakdown expected in surface waters and soils
Bioaccumulation Potential: Not thoroughly evaluated, but low water solubility hints at possible bioaccumulation
Mobility in Soil: Probably not very mobile; binds to organic matter
Waste Treatment: Collect solids and put in sealed, labeled hazardous waste containers
Reuse/Recycle: Not recommended due to purity concerns
Incineration: Dispose through licensed chemical waste incinerator with flue gas scrubber
Sewage Prohibition: Do not pour into sink, drain, or natural waterways (violates most disposal codes)
Container Cleaning: Triple-rinse containers and send to proper waste handling facility; retain all rinsate as hazardous waste
