Chemical Name: Guanidine Nitrate
Synonyms: Guanidinium Nitrate
CAS Number: 506-93-4
Recommended Use: Intermediate in chemical synthesis, propellants, gas generators
Manufacturer: Information varies based on supplier; usually found on label
Emergency Contact: Refer to local emergency telephone number as listed on supplier info
Classification: Explosive (Division 1.1), Oxidizer, Acute Toxicity, Eye Irritant
Signal Word: Danger
Hazard Statements: May explode under heat or fire; toxic if swallowed or inhaled; causes serious eye irritation; can severely damage skin or eyes on contact; reacts with reducing agents
Pictograms: Explosive, Flame over Circle, Skull and Crossbones, Exclamation Mark
Precautionary Statements: Do not breathe dust or fumes; keep away from heat and flames; wear protective gear including gloves, goggles, respirators; wash hands after handling
Substance: Guanidine Nitrate
Purity: Typically greater than 98%
Impurities: Water, traces of nitrite, decomposition products may include cyanamide, ammonia
Inhalation: Move person to fresh air immediately, supply oxygen if breathing is difficult, seek medical attention without delay
Skin Contact: Remove contaminated clothing, wash skin with plenty of water and soap, get medical help for severe irritation or burns
Eye Contact: Rinse with water for at least 15 minutes, hold eyelids open, get medical advice
Ingestion: Rinse mouth, do not induce vomiting, seek prompt medical attention, watch for signs of poisoning such as headache, dizziness, convulsions
Suitable Extinguishing Media: Use water spray, fog, or flooding volumes for cooling. Do not use dry chemical or CO2 as these may not control explosive reaction
Special Hazards: Vigorous decomposition when heated, releases toxic nitrogen oxides, possible explosion even without direct flame
Firefighting Instructions: Approach from upwind, firefighters should wear full protective suit and self-contained breathing apparatus, evacuate surrounding area, avoid water runoff into drains
Personal Precautions: Evacuate area, ventilate space, prevent dust formation, use protective gear such as gloves, coveralls, eye and respiratory protection
Environmental Precautions: Prevent entry to drains and waterways, notify authorities if contamination occurs
Cleanup Methods: Sweep up gently, avoid creating dust clouds, shovel into suitable containers, wash spill area with lots of water after material removal, dispose of in accordance with local regulations
Handling: Avoid direct contact, work in well-ventilated areas, use spark-proof tools and grounding; ground all equipment before use, never smoke or have open flames nearby, avoid mechanical shocks or friction
Storage: Store in a dry, cool, well-ventilated location away from direct sunlight, heat, and combustible materials, keep container tightly closed and clearly labeled, segregate from acids, reducing agents, and organic matter; access should be limited to trained personnel only
Exposure Limits: No ACGIH or OSHA PEL established, but minimize exposure to dust
Engineering Controls: Use local exhaust ventilation, ensure proper explosion-proof electrical equipment
Personal Protective Equipment: Gloves (nitrile or neoprene), chemical-proof goggles, face shield, lab coats or chemical resistant aprons, proper dust masks or respiratory protection conforming to NIOSH standards
Hygiene Measures: Wash thoroughly after handling, never eat, drink, or smoke in work area, remove contaminated clothing promptly
Appearance: White crystalline powder
Odor: Odorless
Melting Point: Around 213°C (decomposes)
Solubility: Highly soluble in water
pH (aqueous solution): Slightly acidic to neutral
Density: Around 1.44 g/cm3 at 20°C
Vapor Pressure: Negligible at room temperature
Auto-ignition Temperature: Decomposes before ignition
Explosive Properties: Explosive under heat, shock, or impact; risk increases in presence of organic materials
Chemical Stability: Stable at low temperature and when dry, sensitive to heat, impact, and contamination
Incompatible Materials: Strong acids, strong bases, reducing agents, organic materials, combustible substances
Decomposition Products: Produces nitrogen oxides, ammonia, carbon oxides on decomposition
Hazardous Reactions: Possible runaway polymerization or explosion in event of contamination or inappropriate handling
Acute Toxicity: Harmful by ingestion and inhalation; LD50 (oral, rat) approx. 800 mg/kg
Skin and Eye Contact: Causes severe eye irritation, possible burns; skin contact leads to redness or dermatitis
Chronic Exposure: Repeated contact may lead to allergic skin responses, neurological symptoms, kidney or liver damage
Other Effects: Overexposure may cause headaches, nausea, confusion, or convulsions; watch for symptoms and seek medical advice on persistent exposure
Toxicity: Harmful to aquatic organisms; no direct data but related compounds impact fish and invertebrates negatively
Persistence and Degradability: Limited data, but nitrates and guanidine derivatives are persistent in water systems
Bioaccumulation Potential: Not likely to bioaccumulate significantly, breakdown produces nitrogen-rich compounds which may lead to eutrophication in water bodies
Mobility in Soil: High solubility in water increases risk of groundwater contamination
Other Hazards: Large spills create local toxicity for plants and animals; harmful to wastewater treatment processes
Waste Disposal: Dispose of as hazardous waste, use licensed waste management contractors
Methods: Incineration under controlled conditions with scrubbers for nitrogen oxides, or chemical neutralization by specialists. Do not landfill or release untreated waste to environment
Precautions: Clearly label and seal all disposal containers; personnel must use full protective gear when handling or transporting waste materials containing guanidine nitrate
UN Number: 1467
Proper Shipping Name: Guanidine Nitrate
Transport Hazard Class: 4.1 (Flammable Solid), 1.1 (Explosive, if in large bulk)
Packing Group: II
Labels: Explosive, Oxidizer, Toxic as needed
Special Precautions: Secure all cargo, avoid stacking, segregate from fuels or other oxidizers, documentation must match regulatory requirements, vehicle placarding required for bulk transport
Regulatory Bodies: Subject to IMDG, IATA, DOT, ADR regulations
TSCA: Listed on US TSCA Inventory
REACH: Noted under European regulations, subject to registration
SARA Title III: Reportable quantity specified under CERCLA for nitrate compounds
Other National Laws: Regulated as hazardous material in most countries; additional state or regional restrictions may apply on storage, transportation, and usage based on risk of explosion or contamination
Workplace Labeling: GHS-compliant pictograms and statements required for all packed quantities; employers must provide regular safety training and access to MSDS
