Safety Profile
Poison by ingestion, skin contact, and intraperitoneal routes. Moderately toxic by subcutaneous route. Mildly toxic by inhalation. An experimental teratogen. Experimental reproductive effects by inhalation. A skin irritant. Mutation data reported. A very dangerous fire hazard when exposed to heat, flame, or oxidizers. Can react vigorously with oxidzing materials. To fight fire, use alcohol foam, CO2, dry chemical. Explodes on contact with 1- perchloryl-piperidme, dqanofurazan, N- nitrosoacetadde. When heated to decomposition it emits highly toxic fumes of NOx. Used in agriculture and pharmaceuticals, and as an intermediate for rubber accelerators. Used in production of drugs of abuse.

Hazard Information

General Description
A clear colorless liquid with a pepper-like odor. Less dense than water, but miscible in water. Will float on water. Flash point 37°F. Melting point-15.8°F (-9°C). Boiling point 222.8°F (106°C). May severely irritate skin and eyes. May be toxic by ingestion and inhalation. Vapors heavier than air. Used to make rubber and as a solvent.
Reactivity Profile
PIPERIDINE(110-89-4) neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides.
Air & Water Reactions
Highly flammable. Miscible in water.
Health Hazard
Strong local irritant and may cause permanent injury after short exposure to small amounts. Ingestion may involve both irreversible and reversible changes. 30 to 60 mg/kg may cause symptoms in humans.
Potential Exposure
Piperidine is used in agriculture and pharmaceuticals; intermediate for rubber accelerators; as a solvent; as a curing agent for rubber and epoxy resins; catalyst for condensation reactions; as an ingredient in oils and fuels; complexing agent; manufacture of local anesthetics; in analgesics; pharmaceuticals, wetting agents; and germicides; synthetic flavoring. Not registered as a pesticide in the Unied States.
First aid
If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit. Medical observation is recommended for 2448 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy.
Fire Hazard
Piperidine evolves explosive concentrations of vapor at normal room temperatures. When heated to decomposition, PIPERIDINE emits highly toxic fumes of nitrogen oxides. Dangerous, when exposed to heat, flame, or oxidizers. Avoid 1-Perchlorylpiperidine and oxidizing materials. Piperidine is a reactive compound and forms complexes with the salts of heavy metals. PIPERIDINE evolves explosive concentrations of vapor at normal room temperatures. Keep away from igniting sources and heat.
Shipping
UN2401 Piperidine, Hazard Class: 8; Labels: 8-Corrosive material, 3-Flammable liquid.
Incompatibilities
Piperidine is a highly flammable liquid. Vapor may form explosive mixture with air (at room temperature). A medium-strong base. Reacts violently with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. Piperidine neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides.
