Chemical Name: O,O-Diethyl-N-1,3-Dithietan-2-Ylidenephosphoramide
Chemical Formula: C6H14NOPS2
Appearance: Pale yellow liquid or crystalline solid, depending on storage temperature
Odor: Faint, chemical-like
Common Uses: Research labs, potential intermediate in organic synthesis
Physical Hazards: Flammable, moderate risk of explosive decomposition if heated rapidly or exposed to open flame
Health Hazards: Toxic through inhalation, skin absorption, and ingestion; may irritate skin and eyes; extended exposure risks include respiratory distress, nausea, and dizziness
Environmental Hazards: Toxic to aquatic life; potential for long-term ecosystem effects from persistent residues
Signal Words: Danger, Toxic, Environmental Hazard
Main Ingredient: O,O-Diethyl-N-1,3-Dithietan-2-Ylidenephosphoramide (purity above 95%)
Impurities: Trace amounts of related organophosphorus compounds, potential for sulfur-containing byproducts
Inhalation: Move to fresh air. Provide oxygen if breathing is difficult and seek medical attention.
Skin Contact: Remove contaminated clothing, rinse thoroughly with running water, wash with soap, watch for delayed symptoms.
Eye Contact: Flush with water for at least 15 minutes, keep eyelids open, consult an eye specialist.
Ingestion: Rinse mouth, do not induce vomiting, seek immediate medical care.
General Precautions: Keep exposed individuals under observation for symptoms such as lightheadedness and vomiting.
Suitable Extinguishing Media: Dry chemical, carbon dioxide, or foam; water spray is less effective and might spread contamination.
Hazardous Combustion Products: Releases toxic gases like phosphorus oxides, nitrogen oxides, sulfur oxides, and possibly ethylene derivatives.
Firefighting Advice: Wear self-contained breathing apparatus, avoid inhaling fumes, contain runoff to prevent environmental contamination.
Personal Precautions: Evacuate area, ventilate, avoid inhalation or skin contact.
Environmental Precautions: Prevent chemical from entering drains, surface water, or soil.
Cleanup Methods: Absorb with inert material such as dry sand, transfer to secure container, clean area with appropriate solvent, and ventilate thoroughly.
Safe Handling: Use under a fume hood, minimize direct contact, employ double-gloving, avoid breathing vapors or dust.
Storage Guidelines: Keep in airtight, clearly labeled containers, store in a dry, ventilated area away from sources of ignition and incompatible chemicals like strong oxidizers and acids.
Shelf-Life Considerations: Monitor for signs of decomposition like discoloration, odor changes, or pressure buildup.
Engineering Controls: Employ local exhaust ventilation, chemical fume hoods, maintain adequate air exchange.
Personal Protective Equipment: Chemical-resistant gloves, lab coat, eye protection with side shields, and, if airborne risk exists, a properly fitted respirator.
Hygiene Measures: Wash hands and exposed skin thoroughly after use, avoid eating or drinking in work area.
Physical State: Liquid or crystalline solid at room temperature
Color: Pale yellow
Odor: Mild, characteristic
Boiling Point: Data not widely available; expect thermal decomposition at moderate heat
Solubility: Low water solubility, soluble in common organic solvents such as acetone and dichloromethane
Vapor Pressure: Unknown; likely low at ambient temperatures
pH: Not applicable (non-aqueous compound)
Chemical Stability: Stable under recommended storage conditions, but sensitive to heat, light, and moisture.
Reactivity: May react with acids, bases, and strong oxidizers.
Hazardous Decomposition: Can release toxic vapors including organophosphorus and sulfur compounds on burning or rapid decomposition.
Acute Effects: Toxic by inhalation, ingestion, and skin contact; symptoms include headache, nausea, dizziness, or respiratory distress.
Chronic Effects: Repeated exposure may cause damage to liver, kidneys, or nervous system.
Sensitization: Risk of allergic skin reaction.
Carcinogenicity/Mutagenicity: Not classified by main regulatory agencies; further studies needed for full risk profile.
Toxicity: Highly toxic to aquatic life, especially to invertebrates and fish.
Persistence and Degradability: May undergo slow degradation in the environment; risks of accumulation in water or sediments.
Bioaccumulative Potential: Likelihood of accumulation in aquatic organisms exists, especially in low-flow or closed systems.
Other Adverse Effects: Disruption of natural microbial communities could occur if released in significant amounts.
Recommended Disposal: Incinerate at specialized, licensed facility capable of safe chemical handling.
Waste Management: Do not dispose via drains or general waste; follow local hazardous waste guidelines.
Packaging: Decontaminate containers before disposal or reuse, label hazardous remains clearly.
UN Shipping Name: Organo-phosphorus compound, toxic, n.o.s.
Hazard Class: Toxic substance
Packing Group: III (moderate hazard)
Precautions: Package securely, segregate from incompatible substances, transport with spill-response kit, avoid exposure to heat or open flame during transit.
Status: Subject to local, national, and international controls on highly toxic and environmentally hazardous chemicals
Worker Safety: Compliance with workplace exposure limits, training requirements, and medical monitoring strongly recommended
Labeling: Clear hazard pictograms, warning statements, risk/safety phrases as mandated by governing authorities
Inventory Listings: Track under chemical safety acts and pollutant registries where applicable
