Chemical Name: Ferric Pyrophosphate
Common Name: Iron(III) pyrophosphate
Concentration: ≥ 98% (typical purity reported for reagent or supplement grade material)
Impurities: Trace iron salts, phosphate derivatives, moisture content as specified by lot analysis
Molecular Weight: 745.21 g/mol
Eye Contact: Flush eyes with running water for several minutes, lift eyelids carefully and remove contact lenses if present, seek medical guidance for ongoing concerns
Skin Contact: Rinse affected area with soap and water, remove contaminated clothing, discontinue use if redness or discomfort develops
Inhalation: Move individual to fresh air, keep breathing passage open, encourage slow breathing, consult a physician if cough or breathing difficulty starts
Ingestion: Rinse mouth, drink water to dilute, avoid inducing vomiting except with medical instruction, call medical professionals if substantial quantity consumed or in case of discomfort
Flammability: Material itself does not ignite but containers exposed to heat may rupture
Suitable Extinguishing Media: Use carbon dioxide, dry chemical powder, or foam for nearby combustibles; apply water spray to cool surfaces
Special Hazards: Iron oxides and phosphorus oxides may form if intense fire occurs
Protective Equipment: Firefighters need full gear with self-contained breathing apparatus
Firefighting Instructions: Evacuate downwind, limit water runoff into drains, isolate area from unnecessary personnel
Personal Precautions: Avoid breathing dust, wear dust mask or respirator, isolate area for cleanup
Environmental Precautions: Keep material out of surface waters and sewers, contain spill with barriers when possible
Cleanup Methods: Sweep up with minimal dust creation, transfer to suitable container for disposal, ventilate area when finished
Handling: Minimize dust generation, apply local exhaust ventilation in bulk transfer zones, wash hands thoroughly after use
Storage: Store in tightly closed containers kept dry and cool, avoid humidity exposure, label containers clearly, separate from incompatible substances such as strong acids or bases
Storage Conditions: Recommended warehouse temperature below 30°C, keep out of sunlight, check for container durability
Exposure Limits: No occupational exposure limit given specifically for ferric pyrophosphate, but iron compounds may be regulated as particulates (refer to OSHA PEL for nuisance dusts: 15 mg/m³ total, 5 mg/m³ respirable fraction)
Engineering Controls: Make use of local exhaust ventilation or fume hoods in production or transfer areas
Personal Protection: Wear safety goggles, lab coat or apron, disposable gloves for routine handling, suitable respirator where dust is possible
Hygiene Practices: Wash before eating, drinking, or leaving the workplace, prevent contamination of clothing by removing uniforms after exposure
Appearance: Pale yellow to light tan powder
Odor: Odorless
pH (suspension in water): Near neutral (typically 7-8 for 1% slurry)
Melting Point: Decomposes above 500°C
Boiling Point: Not applicable (decomposes before boiling)
Solubility: Poorly soluble in water, readily dispersible
Density: Approximately 2.5-3.0 g/cm³
Other Properties: Stable under ambient conditions, not volatile, not explosive, noncombustible solid
Chemical Stability: Stable under ordinary storage and handling conditions
Conditions to Avoid: Excess moisture, acidic or basic environments, elevated temperatures may accelerate decomposition
Incompatible Materials: Strong acids, strong alkalis, powerful oxidizing agents
Hazardous Decomposition: Iron oxides, phosphorus oxides produced under intense heating
Reactivity: Does not react vigorously with most materials under normal use
Routes of Exposure: Inhalation of dust, skin or eye contact, ingestion
Acute Effects: Mild local irritation for sensitive people; high oral doses may cause gastrointestinal discomfort
Chronic Effects: No evidence of chronic health risk at recommended exposure levels
Sensitization: Not reported as sensitizer
Carcinogenicity: Not classified as carcinogen by IARC, NTP, or OSHA
Other Data: Laboratory studies report low toxicity in animal tests; monitor iron parameters for repeated human exposures
Aquatic Toxicity: Limited data available; phosphorus content may promote algae growth in excess
Persistence and Degradability: Inorganic iron compounds persist, but breakdown to natural phosphate and iron
Bioaccumulation: Not anticipated for inorganic salts; residual impact occurs mainly through nutrient enrichment
Mobility in Soil: Binds strongly to soil minerals, low mobility
Environmental Risks: Avoid unnecessary release to environment, prevent runoff into waterways
Waste Handling: Dispose of according to local, state and federal regulations
Unused Material: Place in labeled container, send to chemical waste facility or approved landfill
Contaminated Packaging: Rinse thoroughly, dispose according to regulations or recycle if possible
Precautions: Do not release into sewer or surface water, minimize dust when transferring to waste receptacles
UN Number: Not regulated for transport
Transport Hazard Class: Not considered hazardous for ground, air, or sea shipment
Packing Group: Not assigned
Labeling Requirement: Standard labeling for non-hazardous bulk powders
Special Precautions: Protect packages from moisture and rough handling during transit
Inventory Status: Listed on TSCA, EINECS, and other major chemical inventories
Regulatory Classifications: Not classified as toxic, dangerous, or environmentally hazardous under major international regulations
SARA Title III: Not subject to reporting under Section 313
Other Regulations: Food-grade forms comply with relevant food safety specifications for additives
Workplace Controls: Employers must provide material safety information under OSHA’s Hazard Communication Standard; standard workplace hygiene and engineering controls apply
