CAS Number: 10058-44-3
Synonyms: Iron(III) pyrophosphate
Manufacturer/Supplier: Refer to the sourcing entity responsible for supply. Contact information includes address, emergency telephone number, and company email connected to the safety or quality control department.
Recommended Use: Used in food fortification, pharmaceuticals, and as a laboratory reagent. This compound contributes iron in many fortified food products and supplements, and it plays a role in analytical chemistry routines in laboratory environments.
Restrictions on Use: Intended for industrial, laboratory, or regulated food fortification uses. Improper handling outside of regulated processes can lead to health and safety risks, especially if inhaled or ingested in quantities outside safe limits.
Classification: Not typically classified as hazardous under GHS guidelines for standard concentration levels. Prolonged exposure or excessive handling may present specific risks.
Signal Word: None required for most uses, although it’s smart to maintain basic caution.
Hazard Statements: May cause mild eye, skin, or respiratory tract irritation; inhalation of dust can lead to sneezing or coughing; ingestion in large quantities can result in gastrointestinal discomfort.
Pictograms: None officially mandated, but in-house documentation can show the exclamation symbol to highlight irritation risk.
Precautionary Statements: Avoid breathing dust. Wash exposed skin thoroughly after handling. Wear protective clothing in high-dust settings. Use local exhaust ventilation to suppress airborne particulates.
Chemical Name: Ferric Pyrophosphate
Common Name/Synonyms: Iron(III) pyrophosphate
CAS Number: 10058-44-3
Ingredient Content: 97-100% ferric pyrophosphate; trace moisture and other iron compounds may be present based on manufacturer process controls.
Inhalation: Remove to fresh air; if coughing or irritation persists, seek medical attention. Avoid further exposure during recovery.
Skin Contact: Wash affected area with soap and water. Remove contaminated clothing and launder before reuse. If irritation develops, consult a physician.
Eye Contact: Rinse cautiously with water for several minutes. Remove contact lenses if present. Continue rinsing. If redness or discomfort persists, obtain medical evaluation.
Ingestion: Rinse mouth with water. Do not induce vomiting unless instructed by a physician. Seek medical support if a large amount has been swallowed or gastrointestinal symptoms emerge.
Most Important Symptoms: Mild irritation of eyes, airways, or skin; abdominal upset if ingested in significant quantity.
Suitable Extinguishing Media: Water spray, dry chemical, carbon dioxide, or foam are all suited for fires involving this solid.
Specific Hazards Arising from Chemical: This compound itself does not ignite easily. Thermal decomposition can produce oxides of iron and phosphorus. Dust may slightly intensify a fire in the presence of strong oxidizers.
Special Protective Equipment: Firefighters should wear standard self-contained breathing apparatus and protective clothing to prevent exposure to fumes and dust.
Advice for Firefighters: Move containers from fire area if safe to do so. Use water spray to cool unopened containers. Limit entry to area until fire is fully extinguished and smoke is cleared.
Personal Precautions: Don’t breathe dust. Wear gloves, goggles, and dust mask. Evacuate unnecessary personnel from area.
Environmental Precautions: Prevent large quantities from entering soil, waterways, or drainage systems. Small quantities pose minimal hazard but good practice keeps all chemicals out of the environment.
Methods for Containment and Cleaning Up: Collect powder using a dustless method such as damp cloth or HEPA vacuum. Avoid creating dust clouds. Place material in appropriate container for disposal. Clean spill site with water after collection.
Precautions for Safe Handling: Wear appropriate personal protective equipment. Prevent generation of dust. Wash hands and face after handling.
Conditions for Safe Storage: Store the product in a tightly closed container away from incompatible materials (such as strong acids, strong bases, and oxidizers) and moisture. A cool, dry, well-ventilated place is essential.
Incompatible Materials: Strong acids, strong bases, and oxidizing agents can trigger decomposition.
Occupational Exposure Limits: No specific OSHA or ACGIH exposure limits established for ferric pyrophosphate; treat as nuisance dust (OSHA PEL for particulates not otherwise regulated: 15 mg/m³ total dust, 5 mg/m³ respirable fraction).
Engineering Controls: Use local exhaust ventilation for dusty processes.
Personal Protective Equipment: Safety glasses with side shields, lab coat or coveralls, gloves for routine handling, NIOSH-approved particulate respirator where necessary.
Environmental Controls: Minimize discharge to sewers or waterways.
Appearance: Pale yellow-brown powder
Odor: Odorless
pH (suspension in water): Around 6-8
Solubility in Water: Practically insoluble
Melting Point: Decomposes before melting
Boiling Point: Not applicable
Bulk Density: Approximately 0.6–1.2 g/cm³
Vapor Pressure: Not applicable
Partition Coefficient (N-octanol/water): Not determined
Explosive Properties: None
Oxidizing Properties: Not an oxidizer
Chemical Stability: Stable under standard conditions; prolonged exposure to humidity can cause slow hydrolysis.
Reactivity: Reacts with strong acids, strong bases, and oxidizers; generates iron and phosphate salts.
Conditions to Avoid: High humidity, heating above 100°C, and contact with incompatible materials.
Hazardous Decomposition Products: Iron oxides, phosphorus oxides.
Polymerization: Product does not undergo hazardous polymerization.
Acute Toxicity: Low oral toxicity based on available animal data; large ingested amounts can cause nausea, vomiting, abdominal pain.
Skin/Eye Irritation: Mild, transient irritation to skin and eyes is possible. Prolonged or repeated contact, especially with dust, increases risk.
Respiratory Effects: Inhalation of dust may cause coughing or sneezing. Chronic exposure to high levels of iron compounds can contribute to lung issues, but ferric pyrophosphate is not highly bioavailable through the lungs.
Carcinogenicity: No component listed as a carcinogen by IARC, NTP, or OSHA.
Mutagenicity/Teratogenicity: No evidence in available studies confirms mutagenic or teratogenic effects in humans or animals at exposure levels expected during normal usage.
Toxicity to Aquatic Life: Low toxicity expected; iron and phosphate are naturally found in water and soils. Massive discharges may disrupt nutrient balance, which could trigger algae blooms.
Persistence and Degradability: Inorganic salts, not readily biodegradable. Breaks down to iron and phosphate under natural conditions.
Bioaccumulation Potential: Bioaccumulation unlikely due to low solubility and low absorption by aquatic organisms.
Mobility in Soil: Poorly mobile due to low water solubility, binds strongly to soil particles and sediments.
Other Adverse Effects: Excess amounts may contribute to localized changes in soil or water chemistry, but controlled disposal virtually eliminates this risk.
Waste Treatment Methods: Dispose of product and any contaminated waste as non-hazardous solid waste or through an approved chemical disposal contractor.
Contaminated Containers/Packaging: Triple rinse then offer for recycling or disposal per local, regional, or national regulations.
Environmental Precautions: Avoid release to the environment; prevent waterway and sewer system contamination.
Special Disposal Notes: Refer to local, state, or national regulations for complete, responsible disposal details, especially in the case of significant quantities.
