Chemical Name: Magnesium Diamide
Chemical Formula: Mg(NH2)2
Common Synonyms: Magnesium amide
Appearance: Off-white to light gray powder
Odor: Slight ammonia-like smell, noticeable on opening sealed containers
Main Uses: Laboratory reagent, catalyst in organic synthesis, hydrogen storage research
Main Dangers: Highly reactive with water, releases ammonia gas
Eye and Skin Risk: Corrosive, causes burns with direct contact
Respiratory Risk: Ammonia fumes irritate lungs, cough and difficulty breathing follow exposure
Environmental Impact: Damages aquatic life if it escapes into waterways
Flammability: Reacts violently with moisture, may ignite under certain conditions
Status: Classified as hazardous under many safety standards for its reactivity and toxicity
Active Ingredient: Anhydrous magnesium diamide, typically over 98% by weight
Impurities: Small traces of magnesium oxide and ammonia, often from incomplete reaction or degradation
Physical State: Solid in pure granular or powdered form
Chemical Reactivity: Base; reacts readily with acids and water
Inhalation: Move to fresh air quickly, seek help if dizziness or cough persists
Skin Contact: Wash exposed area thoroughly with plain water, remove any contaminated clothing
Eye Contact: Flush with gently running water for at least fifteen minutes, avoid rubbing
Ingestion: Rinse mouth, do not induce vomiting, get direct medical attention as soon as possible
Medical Notes: Treatment responds best to immediate action, because burns from alkaline substances deepen with delay
Fire Hazards: Reacts with water, generating heat and ammonia gas, which becomes flammable
Suffocation Risk: Decomposes to give off ammonia; use self-contained breathing equipment
Suitable Extinguishing Media: Class D dry powder; avoid water and foam extinguishers which escalate the hazard
Special Precaution: Move other chemicals far from the scene; magnesium amide burning can scatter embers or dust
Personal Precautions: Use full face shield, gloves, protective suit to avoid any contact
Environmental Protection: Block chemicals from drains or water sources
Containment: Sweep up with non-sparking tools, collect in dry, air-tight container
Cleanup: Ventilate area thoroughly after removal, check for lingering dust with ammonia sensors
Handling Advice: Open containers only in dry, well-ventilated rooms, away from any open water or sources of humidity
Storage Conditions: Keep in tightly sealed glass or lined steel drums, under inert gas if possible
Segregation: Store away from acids, organics, water and oxidizers, which all increase risk
Labeling: Mark storage areas with clear hazard warnings, restrict non-essential access
Ventilation: Strong local exhausts above work areas lower fume levels
Hand Protection: Nitrile or thick PVC gloves resist amide attack
Eye and Face Protection: Lab goggles with full-face shield guard against splashes
Respiratory Protection: Use ammonia-rated respirators for open-handling or spill clean-up
Clothing: Long sleeves and closed footwear essential for safe handling in the lab or shop
Physical Form: Fine, slightly grainy powder or small crystals
Melting Point: Decomposes before melting
Boiling Point: Not applicable (breaks down with heat)
Solubility: Insoluble in most common solvents, reacts violently with water
Odor Threshold: Detectable ammonia smell becomes sharp well below hazardous limits
Density: Ranges from 1.2 to 1.4 g/cm3, depending on powder compactness
Chemical Stability: Stable in sealed, moisture-free environment
Dangerous Reactions: Exposed to water, alcohols or acids, releases heat and caustic ammonia
Compatible Materials: Store in lined, non-reactive containers made of glass or certain engineered plastics
Conditions to Avoid: Humidity, heat, sparks, acids, oxidizing chemicals
Acute Effects: Causes severe skin and eye burns quickly
Inhalation Hazard: Even a short time with airborne dust or fumes irritates airways, leads to coughing and possible chemical pneumonia
Chronic Symptoms: Prolonged low-level exposure sometimes damages respiratory tract
Sensitization: Not known to cause allergic reaction
Carcinogenicity: No consistent link found, still not recommended for routine exposure
Aquatic Toxicity: Magnesium diamide escaping into streams or ponds elevates pH, threatens fish and crustaceans
Persistence: Reacts fast, but leaves behind ammonia and insoluble magnesium hydroxide
Soil Impact: Damages local soil microbiology, especially in high-traffic industrial yards
Bioaccumulation: Not expected to build up in animal tissue, but ammonia affects plant roots
Preferred Disposal: Treat with excess weak acid in a controlled, ventilated setting by trained professionals
Prohibited Methods: Never dump in landfill or drains, never burn with regular waste
Packaging: Send only in sealed, labeled containers to licensed handlers familiar with reactive chemicals
Legal Restrictions: Many localities require notification for bulk disposal
Transport Mode: Ship by ground in solid, sealed drums; air transport discouraged unless absolutely necessary
Labeling: Mark as highly reactive, keep away from water at all times
Packaging: Use secondary containment; single-walled bags fail too often in changing temperatures
Regulatory Status: Subject to rules for hazardous solids; carriers sometimes require advance notification
Restrictions: Broadly restricted under chemical safety and occupational health standards
Permissible Exposure Limits: Agencies list low tolerance values for ammonia byproduct
Environmental Rules: Disposal into groundwater, surface water or sewage prohibited in most developed regions
Reporting Requirements: Many workplaces must track and report spills or releases above set limits
