Impurities: Not classified as hazardous under present lab conditions
Inhalation: Immediate transfer to fresh air, monitor for breathing difficulties, provide artificial respiration if necessary, seek professional medical help
Skin Contact: Remove contaminated clothing, quick rinse skin with running water for 15 minutes minimum, consult medical staff if irritation persists
Eye Contact: Rinse with water, lift eyelids to flush, do not allow patient to rub eyes, monitor for ongoing symptoms
Ingestion: Rinse mouth with water, do not induce vomiting, give water to drink only if fully conscious, emergency medical attention recommended
Major Symptoms and Effects: May cause irritation, shortness of breath, redness, headache, nausea, report all exposures to your supervisor immediately
Suitable Extinguishing Media: Carbon dioxide, foam, dry chemical powder, use water spray to cool containers
Unsuitable Media: Direct water jet can spread flammable liquid
Hazardous Combustion Products: Nitrogen oxides, carbon monoxide, carbon dioxide, unstable organic fragments
Protective Gear: Chemical splash suit, self-contained breathing apparatus to prevent inhalation
Advice for Firefighters: Evacuate area, approach upwind, prevent runoff from contaminating drains
Other Considerations: Containers can pressurize on heating, remove from fire area if safe to do so
Personal Protection: Use nitrile gloves, splash goggles, chemical apron, ensure suitable ventilation
Spill Cleanup: Absorb spillage with inert material like sand or earth, collect residue in sealable containers, avoid direct skin or eye contact, keep away from open flames
Environmental Precautions: Prevent leaks from entering sewers, storm drains, soil, or water bodies; use barriers or diking methods
Methods for Disposal: Refer to local chemical waste authority, incinerate if permitted
Small Spills: Wipe up with absorbent towels, wash residue with soap and water; all waste to chemical waste disposal
Handling Precautions: Avoid inhaling vapors, prevent contact with skin and eyes, never eat, drink, or smoke while handling chemicals
Safe Practices: Open containers in fume hood, work with minimum quantities, use non-sparking tools
Storage Requirements: Flammable cabinet, tightly sealed containers, away from oxidizing agents, strong acids, heat, ignition sources
Incompatible Storage: Separately from oxidizers, chlorinated compounds, strong acids
Storage Temperature: Ambient to cool, ensure dry area with minimal fluctuation
Exposure Limits: No specific occupational exposure limits set by OSHA, NIOSH, or ACGIH; minimize airborne concentration as low as possible
Engineering Controls: Fume hood or local exhaust ventilation in all cases
Personal Protective Equipment: Chemical-resistant gloves (nitrile/rubber), safety goggles, long-sleeve lab coat, splashproof face shield for large quantities
Respiratory Protection: Wear NIOSH-approved respirator if vapor concentration rises above comfort threshold
General Hygiene: Wash hands and forearms after use, separate contaminated clothing, avoid accidental ingestion
Appearance: Clear to yellowish liquid, may darken on exposure to air
Odor: Amine-like, pungent
Odor Threshold: Not well-established, detectible at low concentrations
pH: Not applicable, non-aqueous
Melting Point/Freezing Point: -63°C (approx.)
Boiling Point/Range: 194°C (approx.)
Flash Point: 68°C (closed cup)
Evaporation Rate: No reliable value, slower than acetone
Flammability: Flammable liquid, vapor spreads along surfaces
Vapor Pressure: 0.4 mmHg at 20°C
Vapor Density: Heavier than air (estimate: 3.8)
Relative Density: 0.98 g/cm3
Solubility in Water: Moderately soluble
Partition Coefficient (n-octanol/water): Estimate: logP 1.7
Decomposition Temperature: Not established, decomposes on strong heating
Viscosity: Low, spreads easily
Chemical Stability: Stable under normal laboratory conditions, decomposes in long-standing air exposure or strong sunlight
Reactivity: Reacts exothermically with strong acids, oxidizers, and some alkylating agents
Hazardous Reactions: Danger of fire with oxidizing materials, forms no polymer under basic storage
Conditions to Avoid: Prolonged heating, open flames, strong oxidants, static discharge
Hazardous Decomposition: Nitrogen oxides, carbon monoxide, potentially some hydrocarbon fragments
Acute Toxicity: Oral LD50 (rat) estimated 350 mg/kg, no chronic animal studies
Skin Corrosion/Irritation: Causes skin redness, roughness, fleeting burning sensation
Eye Damage/Irritation: Redness, stinging, watering on direct contact
Respiratory Sensitization: Brief cough, upper respiratory discomfort if inhaled
Germ Cell Mutagenicity: No data available
Carcinogenicity: No evidence from animal studies
Reproductive Toxicity: Not known, no fertility studies
Target Organ Effects: Possible mild liver and kidney stress at high doses
Other Information: All exposures should be recorded; treat symptoms quickly and report to regulatory authority if unexpected effects occur
Toxicity to Aquatic Organisms: Data limited, acute toxicity suspected for small aquatic species
Persistence/Biodegradability: Not expected to be persistent, moderate biodegradation in standard soil and water tests
Bioaccumulative Potential: Moderate risk due to partition coefficient
Mobility in Soil: Liquid is slightly mobile, possible leaching in moist, non-clay soils
Other Adverse Effects: Unintended release can disrupt aquatic invertebrates and soil microbes; collect spills and avoid direct entry into drains or waterways
Waste Handling: Never pour into drains or trash, collect waste in sealed chemical containers
Methods of Disposal: Authorized waste incinerator, thermal treatment site, or licensed chemical waste processing facility
Container Cleanup: Triple rinse, send empty containers for chemical recycling or high-temperature incineration
Disposal Regulations: Follow local, regional, and national hazardous waste laws; document all disposals
