Chemical Name: Tris(1-chloro-2-propyl) phosphate
CAS Number: 13674-84-5
Concentration: >97% (w/w)
Impurities: Trace of isopropylated mono- and dichloropropyl phosphates, other minor organophosphate components
Additives: Commonly supplied without additives. Purity should be confirmed by the supplier certificate.
Eye Contact: Rinse cautiously with water for several minutes. Remove contact lenses if present and easy to do. Seek medical advice if irritation persists.
Skin Contact: Wash skin thoroughly with soap and water. Take off contaminated clothing and wash before reuse. If a rash or persistent irritation shows up, get medical attention.
Inhalation: Move person to fresh air and keep comfortable. If respiratory symptoms arise, call a doctor.
Ingestion: Rinse mouth. Do not induce vomiting. Seek prompt medical attention if feeling unwell.
Suitable Extinguishing Media: Use foam, dry chemical powder, CO₂, or water spray for small fires.
Specific Hazards: Burning releases toxic and corrosive gases including hydrogen chloride, phosphorus oxides, and carbon oxides.
Protective Equipment for Firefighters: Wear self-contained breathing apparatus and full protective clothing.
Firefighting Advice: Keep containers cool with water spray if safe to do so. Avoid runoff from fire control entering water sources.
Personal Protection: Wear chemical-resistant gloves, splash goggles, and ensure good ventilation or use respiratory protection if necessary.
Spill Cleanup Methods: Cover spill with inert absorbent material (like sand or vermiculite). Collect waste in labeled containers for disposal.
Environmental Precautions: Avoid entry into drains or watercourses. Notify authorities if spill enters environment.
Handling Damaged Containers: Use tools and equipment made from materials compatible with organophosphates to handle leaks.
Handling: Use only with adequate ventilation or in a chemical fume hood. Avoid breathing mist or vapor. Avoid contact with eyes and skin.
Storage: Keep containers tightly closed in a cool, dry, well-ventilated place. Store away from incompatible substances such as strong oxidizers and strong acids. Do not store near sources of ignition or direct sunlight. Store at temperatures below 40°C. Use secondary containment where practical.
Exposure Limits: No established US OSHA PEL or ACGIH TLV for TCPP. Limit workplace exposure as much as possible.
Engineering Controls: Install local exhaust or general room ventilation. Use fume hoods for weighing or pouring.
Personal Protective Equipment: Wear impervious gloves (such as nitrile), chemical-resistant apron, safety goggles or face shield, and if vapor exposure risk exists, use an organic vapor respirator.
Hygiene Practices: Wash hands and any exposed skin thoroughly after handling. Remove contaminated clothing before leaving work area.
Appearance: Clear or slightly yellowish liquid
Odor: Mild
Odor Threshold: No data available
Boiling Point: 244°C
Melting Point: Not applicable (liquid at room temperature)
Flash Point: 232°C (closed cup)
Solubility: Insoluble in water, miscible with many organic solvents
Density: Around 1.28 g/cm³ at 20°C
Vapor Pressure: <0.01 mm Hg at 20°C
pH: Not applicable (non-aqueous liquid)
Partition Coefficient (n-octanol/water): log Kow 2.59-2.66
Viscosity: 65-70 mPa.s at 25°C
Chemical Stability: Stable at room temperature in closed containers under normal storage.
Incompatible Materials: Strong oxidizing agents, strong acids, bases.
Hazardous Decomposition Products: Produces toxic gases like hydrogen chloride, phosphorus oxides, and carbon monoxide if heated to decomposition.
Polymerization: No data found for hazardous polymerization.
Reactivity: Avoid mixing with incompatible substances to prevent hazardous situations.
Likely Routes of Exposure: Eye and skin contact, ingestion, inhalation of aerosol or mist.
Acute Toxicity: Oral LD50 (rat): 630-1180 mg/kg
Skin Irritation: Can cause mild irritation.
Eye Irritation: Causes significant eye irritation.
Respiratory Effects: Prolonged inhalation can produce mild irritation or respiratory discomfort.
Sensitization: May trigger allergic skin reactions in sensitive individuals.
Chronic Effects: Repeated or prolonged exposure can cause skin dryness or cracking. Yet, long-term carcinogenicity tests on TCPP have mixed results and regulatory agencies are still reviewing data.
Mutagenicity and Reproductive Toxicity: Most studies suggest low mutagenic potential, but ongoing reviews continue among regulatory bodies.
Acute Aquatic Toxicity: Moderately toxic to aquatic organisms. LC50 (fish, 96hr): 56 mg/L.
Persistence and Degradability: Degrades slowly in the environment; persistent in water and sediment.
Bioaccumulation: Moderate potential for bioaccumulation in aquatic species. Bioconcentration factor (BCF): 5-37
Mobility: Low in soil, tends to adsorb to sediment.
Other Environmental Data: Breakdown products can be more persistent. Multiple European agencies include TCPP on lists for monitoring due to water pollution risk. Small spills carry risk for downstream environmental harm if uncontrolled.
Disposal Methods: Incinerate in a chemical incinerator equipped with scrubber or send to licensed hazardous waste facility. Do not discharge to drains or natural waters.
Container Disposal: Empty containers must be triple rinsed and punctured before disposal according to local regulations.
Special Considerations: Handle waste in accordance with all environmental regulations. Spent material and wash liquids often classified as hazardous waste (US EPA Hazardous Waste Code U207 for related compounds; confirm with local guidance).
UN Number: Not assigned for TCPP
Transportation Classification: Not regulated as a dangerous good for major international transport modes (IMDG, IATA, DOT), but check local requirements for environmental hazard labeling.
Packing Group: Not applicable
Environmental Hazards: Not classified, but spill could create local aquatic hazard.
Special Precautions: Transport in tightly closed, properly labeled containers. Protect from physical damage and keep separated from food or animal feed shipments.
Emergency Guide Number: Refer to transport carrier’s guide for accidental release or fire during shipment.
US Regulations: Listed on TSCA Inventory. Not classified as hazardous under OSHA Hazard Communication Standard (29 CFR 1910.1200) but subject to SARA 313 reporting for toxic chemicals.
EU Regulations: Listed in EINECS/REACH. Candidate for further regulation as a possible substance of concern. Subject to workplace safety limits (consult member state requirements).
