Chemical Name: Tetrakis(4-fluorophenyl)borate sodium dihydrate
Synonyms: Sodium tetrakis(4-fluorophenyl)borate dihydrate
CAS Number: 145926-45-0
EC Number: Not available
Purity: Usually above 98% in laboratory reagents
Hazardous Components: Main body is the borate salt, no additional listed hazardous impurities at standard concentrations.
Inhalation: Move the affected person to fresh air and keep them at rest. If symptoms of respiratory distress appear, seek medical advice.
Skin Contact: Remove contaminated clothing, wash skin with soap and water for several minutes. Persistent irritation signals a prompt visit to a healthcare provider.
Eye Contact: Rinse eyes gently with water for at least 15 minutes, lifting the upper and lower eyelids. Remove contact lenses if present and easy. Immediate medical consultation recommended.
Ingestion: Rinse mouth with water. Do not induce vomiting unless instructed by medical personnel. Seek medical attention if feeling unwell.
Notes to Physicians: Treat based on symptoms; there are no known specific antidotes to this compound, focus on supportive measures and symptomatic relief.
Suitable Extinguishing Media: Carbon dioxide, dry chemicals, foam, or water spray. Select agents based on surroundings and the nature of the adjacent fires.
Hazardous Combustion Products: Oxides of carbon, fluorinated aromatic compounds, boron oxides, sodium oxides. Inhalation risk from hazardous gases, especially in an enclosed setting.
Special Protective Equipment: Firefighters should wear self-contained breathing apparatus with full protective gear to protect against potential toxic fumes, splash, or skin contact risks.
Fire and Explosion Hazards: Product is not highly flammable but heating can produce irritant or toxic vapors. Avoid inhalation of fumes or runoff from firefighting.
Personal Precautions: Equip personnel with nitrile gloves, chemical splash goggles, lab coats, and respiratory protection if dust or aerosol forms. Evacuate non-essential individuals until decontamination finishes.
Environmental Precautions: Contain spill to prevent runoff into soil, drains, or surface water. Avoid direct discharge to environment.
Cleanup Methods: Sweep up solid gently to minimize dust, collect in an appropriate closed container for disposal. Clean affected surfaces with water and detergent; ventilate the area thoroughly.
Reference to Other Sections: Review personal protection and disposal provisions in related sections before clean-up.
Precautions for Safe Handling: Avoid generating dust, aerosol, or inhaling powder. Minimize direct contact with skin, face, or eyes by using personal protective equipment.
Safe Storage Conditions: Store in tightly closed, labeled containers in a dry, cool, well-ventilated location away from strong acids and oxidizers. Keep out of reach of untrained individuals.
Incompatible Materials: Avoid storage alongside acids, oxidizing agents, or moisture sources, since these might degrade the chemical.
Handling Advice: Only trained professionals should handle the product in a controlled setting.
Exposure Limits: No specific occupational exposure limits set by OSHA or ACGIH for this compound; limit airborne levels to lowest achievable.
Engineering Controls: Use chemical fume hoods, local exhaust, and closed processes to minimize airborne exposure. Work in a well-ventilated laboratory.
Personal Protective Equipment: Wear safety goggles, gloves made of nitrile rubber or equivalent, and lab coat. Respiratory protection recommended if dust or particulates likely.
Hygiene Measures: Wash hands, face, and exposed skin after handling. Avoid eating, drinking, or smoking in work areas. Remove contaminated clothing before entering public spaces.
Appearance: White to off-white crystalline solid
Odor: Odorless
Molecular Weight: 452.19 g/mol (anhydrous), higher with dihydrate present
pH: Not established for substance in water, expected near neutral
Melting Point: Decomposes before melting above 230°C
Boiling Point: Not applicable (decomposes)
Water Solubility: Slightly soluble
Partition Coefficient: Not experimentally established
Flash Point: Not flammable under normal conditions
Vapor Pressure: Negligible at standard ambient temperature
Decomposition Temperature: Surpasses 230°C, decomposition yields toxic gases
Chemical Stability: Remains stable under standard ambient conditions. Water and heat may gradually encourage degradation.
Reactive Hazards: Reacts with acids; may release toxic or corrosive fumes including hydrogen fluoride when strongly heated.
Conditions to Avoid: Avoid excessive moisture, heat, direct sunlight, and poor ventilation. Store away from acids and oxidizers to prevent destabilization.
Hazardous Decomposition: High temperatures produce boron oxides, sodium fumes, and fluorinated organic vapors.
Acute Toxicity: Data for the sodium salt is limited; estimated oral LD50 for rats could be above 1,000 mg/kg. Ingesting small quantities may irritate mucous membranes and GI tract.
Skin Corrosion/Irritation: Low irritation risk without prolonged or repeated exposure. Broken skin may absorb product.
Serious Eye Damage/Irritation: Significant eye irritant, symptoms include redness, watering, or pain on direct exposure.
Respiratory Sensitization: Dusts could trigger discomfort, especially in sensitive individuals.
Long-Term Effects: No data on reproductive toxicity, carcinogenicity, or chronic exposure specific to this chemical, but care always warranted.
Aquatic Toxicity: No public test data, but borate salts in general may be harmful to aquatic life in significant spills. Diluted concentrations unlikely to persist in moving water.
Environmental Fate: Moderately persistent in soil and water due to low solubility. Not prone to rapid decomposition.
Bioaccumulation: Unlikely to accumulate significantly in organisms given molecule size and water solubility patterns.
Mobility: Low to moderate in soil; particulate form reduces leaching.
Other Hazards: Handle with care to prevent release to watercourses or sanitation drains.
Waste Treatment Methods: Collect in sealed, labeled chemical waste containers and hand over to certified hazardous waste disposal specialists.
Contaminated Packaging: Rinse with water if compatible, then manage as chemical waste. Avoid landfill or incineration without professional assessment.
Legal Authorizations: Disposal must comply with local, regional, and national regulations regarding hazardous chemical disposal.
Precautions: Prevent escape to environment; do not dispose by draining.
UN Number: Not classified under standard transport hazard regulations.
Proper Shipping Name: Chemical for laboratory use; not regulated as dangerous goods when shipped in usual small-packing laboratory quantities.
Hazard Class: No hazard class assigned; treat as general chemical unless transporting kilos or more.
Packing Group: Not assigned
Environmental Hazards: Avoid large volume release during transit.
Special Precautions: Use sealed, labeled vessels; avoid rough handling, shock, excessive heat and moisture during transport.
Local and International Regulations: Not listed by major inventories such as TSCA (US), EINECS (EU) or DSL (Canada) as a controlled substance, but specific country requirements for notification and registration apply.
