Toxicity:Oral-rat LD50: 113 mg/kg; Oral-Mouse LD50: 800 mg/kg
Flammability characteristics:It is flammable in case of open flame, high temperature, oxidant; strong decomposition at high temperature; burning produces irritating smoke
Explosive limit:The substance can readily form explosive peroxides on contact with air. The substance will readily polymerize to dimer with fire or explosion hazard. The reaction is accelerated by peroxides or trichloroacetic acid.
Odor:MONOMERIC FORM HAS TERPENE ODOR IN VAPOR STATE

Air and Water Reactions:No rapid reaction with air No rapid reaction with water
Reactive Group:Hydrocarbons, Aliphatic Unsaturated
Reactivity Alerts:Highly Flammable
Reactivity Profile:CYCLOPENTADIENE is incompatible with strong oxidizing agents. Ignites on contact with oxygen (O2) and ozone (O3). Explodes on contact with fuming nitric acid or a mixture of sulfuric acid and nitrogen tetroxide. Reacts vigorously on contact with potassium hydroxide and other strong bases. Mixtures with air are explosive. Presents a moderate explosion hazard when exposed to heat or flame. Decomposes violently at high temperature and pressure. May form explosive peroxides in storage. Undergoes a spontaneous dimerization at room temperature to give DICYCLOPENTADIENE (C10H12, CAS No: 77-73-6), which is a low-melting solid (melting point: 32.5° C). The reaction is strongly exothermic (Hazardous Chemicals Desk Reference, p. 360 (1987)), but occurs sufficiently slowly that cyclopentadiene can be said to be stable at room temperature. The dimerization accounts for the partial or complete solidification of liquid cyclopentadiene in storage. Polymerization occurs more rapidly and extensively at higher temperatures. When heated to 180-200° C, cyclopentadiene gives polycyclopentadiene, a white waxy solid. Stronger heating breaks down polycyclopentadiene and re-generates the monomeric cyclopentadiene as a vapor. The vapor decomposes violently at higher temperatures and pressures.
Autoignition Temperature:640 °C
Ionization Potential:8.56 eV
Flammable Limits:Class IC Flammable Liquid: Fl.P. at or above 73°F and below 100°F.
Physical Dangers:The vapour is heavier than air.
