Impurities: Minor impurities below 1%, no listed hazardous impurities
CAS Number: 101-02-0
Inhalation: Move to fresh air and keep comfortable, seek medical advice if symptoms develop
Skin Contact: Wash thoroughly with soap and water, remove contaminated clothing
Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses, continue rinsing and seek medical attention
Ingestion: Rinse mouth, do not induce vomiting unless directed by a medical professional, seek prompt medical care
Suitable Extinguishing Media: Foam, dry chemical, carbon dioxide, or water spray
Specific Hazards: Combustible under fire conditions, releases irritating and toxic fumes such as phosphorus oxides
Protective Equipment: Firefighters should wear self-contained breathing apparatus and full protective gear
Firefighting Advice: Cool containers exposed to flames with water spray to prevent pressure buildup and explosion
Personal Precautions: Wear appropriate protective equipment including gloves, goggles, and respirator if required
Environmental Precautions: Prevent entry into waterways, drains, or soil to avoid long-term environmental effects
Cleanup Methods: Absorb spillage with inert material like sand or vermiculite and transfer to containers for disposal; ventilate area thoroughly
Handling: Use in well-ventilated areas, avoid breathing vapors, prevent contact with eyes and skin by using personal protective gear, maintain good workplace hygiene
Storage: Keep containers tightly closed and in a cool, dry, well-ventilated location away from heat, direct sunlight, and incompatible materials such as oxidizers and acids, label all storage containers clearly due to process risk
Exposure Limits: No OSHA or ACGIH specified limits for Triphenyl phosphite, use general ventilation systems
Engineering Controls: Utilize local exhaust ventilation to maintain airborne concentrations below recommended exposure levels
Personal Protection: Wear chemical-resistant gloves, safety goggles, long-sleeved clothing; use an approved respirator if ventilation is inadequate or airborne exposures exceed limits
Hygienic Measures: Wash hands thoroughly after handling and before eating, drinking, or smoking
Appearance: Colorless to pale yellow transparent liquid
Odor: Slight, phenolic
Boiling Point: Approximately 360°C
Melting Point: 19°C
Solubility: Insoluble in water, soluble in most organic solvents
Vapor Pressure: Low at room temperature
Density: 1.183 g/cm3 at 20°C
Flash Point: 230°C (closed cup)
Auto-ignition Temperature: No data
Partition Coefficient (n-octanol/water): log Kow ~ 7 (highly lipophilic)
Chemical Stability: Stable under normal temperatures and storage conditions
Reactivity: Can react with strong oxidizing agents, acids, and alkalis
Decomposition: Decomposes at high temperatures producing phosphorus oxides, phenols, and irritating fumes
Hazardous Polymerization: Will not occur under recommended storage and handling conditions
Acute Toxicity: Oral LD50 in rats reported at >5000 mg/kg, low acute oral toxicity
Skin and Eye Irritation: Causes skin irritation and serious eye irritation, may exacerbate dermal and ocular conditions
Respiratory Tract: Vapors and mists may irritate respiratory tract with coughing or soreness following high exposure
Chronic Effects: Prolonged or repeated exposure may cause dermatitis
Sensitization: Not classified as a sensitizer
Carcinogenicity, Mutagenicity, Reproductive effects: Not listed by IARC, NTP, OSHA as carcinogen, no strong evidence of mutagenicity or reproductive hazards
Ecotoxicity: Harmful to aquatic organisms, may cause long-term adverse effects in the aquatic environment
Persistence and Degradability: Biodegradation is slow, high potential for persistence due to low water solubility and high partition coefficient
Bioaccumulative Potential: High potential for bioaccumulation based on log Kow values
Mobility in Soil: Tends to bind strongly to soil and sediment, low groundwater mobility
Environmental Precautions: Prevent chemical release into surface water, sewers, and soil to limit ecosystem disruption
Waste Disposal: Dispose of as hazardous industrial waste in accordance with local, regional, and national regulations; incineration is preferred where permitted
Container Disposal: Triple rinse empty containers before disposal or recycling, refrain from reuse
Precautions: Do not discharge into drains, surface water, or soil
UN Number: Not regulated for land, air, or sea transport under most international regulations
Transport Hazard Class: Not classified as dangerous good
Packing Group: Not assigned
Special Precautions: Ship in tightly closed containers, avoid strong mechanical shocks and extremes of temperature during transport
US Regulations: Listed on TSCA, no established OSHA PEL or ACGIH TLV, not listed under CERCLA or SARA Title III as a hazardous substance
EU Regulations: Listed in EINECS (EC No. 202-908-4), subject to REACH registration
Other Regulations: Check country-specific chemical inventories and local regulations prior to use; comply with workplace labeling requirements
