Signal word: Danger
Hazard class: Acute toxicity (oral, dermal), eye and skin irritation, possible mutagenicity
Main risks: May cause serious eye damage, skin irritation, respiratory tract irritation, and toxic effects if swallowed
Precautionary statements: Avoid inhaling dust or vapors, use gloves, protective eyewear, and avoid eating or drinking during handling
Main constituent: Dinitroresorcinol
Purity: More than 95% typical in laboratory grades
Impurities: Trace amounts of related nitroaromatics possible from synthesis
Inhalation: Remove to fresh air, monitor for breathing difficulty, seek medical attention for persistent symptoms
Skin contact: Wash immediately with soap and water, remove contaminated clothing
Eye contact: Rinse cautiously with water for several minutes, seek medical help if irritation persists
Ingestion: Rinse mouth, do not induce vomiting, seek medical attention immediately
Suitable extinguishing media: Water spray, foam, carbon dioxide, dry chemical
Hazardous combustion products: Nitrogen oxides, carbon oxides, possibly irritating fumes
Protective equipment: Firefighters should wear self-contained breathing apparatus
Other remarks: Heated material can explode; keep cool with water spray
Personal precautions: Evacuate area, wear respirator, gloves, safety goggles
Environmental precautions: Prevent spillage from entering drains or waterways
Methods for cleanup: Sweep up with non-sparking tools, place in sealed containers, ventilate area
Handling: Use local exhaust ventilation, avoid generating dust, wear appropriate protective equipment
Storage: Store in tightly closed container, in a cool, dry, well-ventilated place, away from heat and incompatible substances, keep separate from oxidizers and reducing agents, minimize quantities for use
Engineering controls: Use fume hood or well-ventilated area
Eye protection: Safety goggles or face shield
Skin protection: Chemical-resistant gloves, long sleeves
Respiratory protection: Dust mask or respirator if dust is present or ventilation is insufficient
General hygiene: Wash hands after handling, do not eat, drink, or smoke near chemicals
Appearance: Yellow crystalline solid
Odor: Faint, often unnoticeable
Melting point: Between 160°C and 170°C
Solubility: Slightly soluble in water, readily soluble in alcohol and ether
Density: About 1.73 g/cm³
Vapor pressure: Low at room temperature
pH: Not relevant for solid
Partition coefficient: Not broadly reported
Decomposition: May decompose explosively at high temperature, releasing toxic gases
Chemical stability: Stable under recommended storage conditions
Reactivity: Can react violently with strong reducing agents
Incompatible materials: Strong oxidizers, strong bases, strong acids
Hazardous reactions: Contact with heat, friction, or impact can lead to explosive decomposition
Routes of exposure: Skin, eyes, inhalation, ingestion
Acute effects: Toxic if swallowed, skin irritant, may cause eye damage, breathing irritation from dust
Chronic effects: Limited data, but long-term exposure to nitro compounds can be linked to liver and kidney damage, possible mutagenicity
Symptoms: Nausea, headache, dizziness, cyanosis (bluish skin), irritation to eyes, skin, respiratory system
Environmental toxicity: Toxic to aquatic life
Persistence: Nitroaromatic compounds tend to persist in soil and water
Mobility: May leach through soil if spilled
Bioaccumulation potential: Low to moderate, but chronic exposure risk for organisms
Other concerns: Avoid releasing material to waterways, consider long-term impacts on soil and groundwater
Methods: Dispose of through incineration in accordance with local, regional, and federal regulations
Precautions: Do not dispose of in drains or uncontrolled landfill
Packaging: Seal tightly, label clearly, transport to facility equipped to handle hazardous chemical waste
