Pyrilamine Specification

General description about Pyrilamine (CAS NO.91-84-9), it is a viscous brown liquid.
Air & Water Reactions: May be sensitive to light. Insoluble in water.
Reactivity Profile: It neutralizes acids to form salts plus water in exothermic reactions. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. May generate flammable gaseous hydrogen in combination with strong reducing agents, such as hydrides.
Health Hazard: Symptoms: Exposure to  Pyrilamine  may cause somnolence, central nervous system depression and gastrointestinal disturbances. It may also cause drowsiness, dryness of the mouth, headache, nausea, tachycardia, urinary retention, nervousness, disorientation, staggering gait, hallucinations, stupor, coma, hyperflexia, tremors, excitement, nystagmus, hyperthermia, convulsions, agranulocytosis and aplastic anemia.
Fire Hazard: Flash point data for it are not available; however, It is probably combustible.
