Chemical Name: Iron Porphyrin
Common Name: Porphyrin iron complex
CAS No.: 14875-96-8
EC No.: Not listed
Purity: Typically above 95% for analytical and research use
Impurities: Residual organic solvents, free porphyrin, ferric salts below 5%
Stabilizers: None needed for storage; some suppliers add trace antioxidants
Inhalation: Move to fresh air. Seek medical attention if symptoms persist like coughing, wheezing, or throat irritation.
Skin Contact: Immediately wash affected area with soap and plenty of water. Remove contaminated clothing. Symptoms such as redness or pain should be monitored.
Eye Contact: Rinse immediately with plenty of water for at least 15 minutes holding the eyelids open. Contact physician if discomfort persists.
Ingestion: Rinse mouth. Do not induce vomiting. Give water if victim is conscious. Seek medical advice if larger quantities swallowed or symptoms develop.
Most Important Symptoms: Cough, sneezing, mild skin or eye irritation, nausea if ingested.
Medical Attention: Physician should monitor for irritation, allergic reactions, and respiratory distress.
Suitable Extinguishing Media: Use carbon dioxide, dry chemical powder, or foam. Water spray can cool but may spread finely dispersed powders.
Unsuitable Extinguishing Media: High-pressure water jets may disperse dust.
Special Hazards: Thermal decomposition may produce oxides of nitrogen, carbon monoxide, carbon dioxide, and iron oxides. Avoid inhaling fumes.
Protective Equipment: Firefighters should use self-contained breathing apparatus and full protective gear.
Advice for Firefighters: Approach from upwind. Move containers from fire area if safe. Cool unopened containers with water.
Explosion Hazards: Finely divided powders may form combustible dust clouds.
Personal Precautions: Wear protective clothing, gloves, and safety glasses. Use a respirator if significant dust is generated.
Environmental Precautions: Prevent large amounts from entering drains, watercourses, or soil.
Method for Cleaning Up: Collect spilled powder with a HEPA vacuum or damp cloths, avoiding dry sweeping. Place collected material in properly labeled container for disposal.
Decontamination: Clean surfaces with mild detergent and water. Dispose of waste in accordance with local, regional, and federal regulations.
In Case of Large Spill: Evacuate unprotected personnel and ventilate area.
Handling: Work in well-ventilated area. Avoid contact with eyes, skin, and clothing. Wash hands thoroughly after handling. Do not eat, drink, or smoke while handling.
Storage Conditions: Store tightly sealed in cool, dry location. Keep away from light, sources of heat, and incompatible substances like strong oxidizers.
Storage Containers: Use chemically resistant, labeled containers. Avoid non-labeled secondary containers.
Storage Temperature: Ambient laboratory conditions, typically 2–25°C. Extended exposure to higher temperatures risks decomposition.
Incompatibilities: Strong acids, alkalis, and oxidizing agents.
Occupational Exposure Limits: No established OSHA/TWA or ACGIH values for iron porphyrin.
Engineering Controls: Use local exhaust or fume hood in areas of dust generation.
Personal Protective Equipment: Chemical-resistant gloves (e.g., nitrile or neoprene), lab coat, safety goggles with side shields.
Respiratory Protection: Dust mask or respirator required in case of inadequate ventilation.
Hygiene Measures: Wash before breaks and at end of workday. Remove contaminated clothing promptly.
Monitoring: Regular environmental sampling if working at larger scales or repeated exposures.
Appearance: Dark purple to black crystalline powder
Odor: Odorless or faint metallic scent
pH: Not determined (insoluble in water)
Melting Point/Range: Decomposes above 300°C
Boiling Point: Not applicable (decomposes before boiling)
Flash Point: Not determined
Flammability: May burn as fine powder
Vapor Pressure: Negligible
Solubility: Slightly soluble in organic solvents like chloroform, insoluble in water
Density: About 1–1.2 g/cm³ (estimated)
Partition Coefficient: Not available
Decomposition Temperature: Above 300°C
Viscosity: Not relevant (solid)
Chemical Stability: Stable under recommended conditions and ambient storage.
Reactivity: Not highly reactive; sensitive to strong oxidizers.
Conditions to Avoid: Extended exposure to strong sunlight or high temperatures.
Incompatible Materials: Avoid contact with strong acids, strong alkalis, and oxidizing agents.
Decomposition Products: Burning or decomposition may release iron oxides, carbon monoxide, nitrogen oxides.
Hazardous Polymerization: Does not undergo hazardous polymerization.
Routes of Exposure: Inhalation, skin, eyes, ingestion.
Acute Toxicity: Not enough human or animal data. Low acute toxicity suspected, periodic exposure may irritate respiratory or digestive tracts.
Chronic Effects: Effects on blood or organs not well studied. No known carcinogenic properties.
Irritation: May cause mild irritation in eyes and on skin.
Allergic Reactions: No known sensitizing effects identified.
Mutagenicity/Teratogenicity: Not tested, assumed negative owing to chemical class.
Other Data: Iron compounds in general may be harmful in high amounts, especially if ingested over long periods.
Aquatic Toxicity: Low risk due to low solubility. Data limited, but structurally similar compounds show minimal impact at typical spill levels.
Persistence/Degradability: May persist as particulate in environment. Not readily biodegradable.
Bioaccumulation: Unlikely due to low water solubility.
Mobility: Stays in soil or sediment under typical environmental conditions.
Other Hazardous Effects: Release of bulk quantities should be contained and reported as required.
Environmental Precautions: Prevent runoff into natural waterways.
Disposal Methods: Dispose as hazardous chemical waste through licensed handler. Incinerate in proper facilities or landfill according to local rules.
Contaminated Packaging: Clean containers may be recycled; otherwise, treat as hazardous waste.
Waste Codes: Assign appropriate RCRA code if mixed with solvents or heavy metals during laboratory use.
Special Precautions: Never dispose down drain or in regular trash; collect for proper handling.
