Regulatory Information
Chemical: 1,3-Pentadiene, 4-methyl-
The New Jersey Worker and Community Right to Know Act requires public and private employers to provide information about hazardous substances at their workplaces. (N.J.S.A. 34:5A-1 et. seq.)
DOT LabelFlammable Liquid
Fire Hazards
Excerpt from ERG Guide 128 [Flammable Liquids (Water-Immiscible)]:
· HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames.
Health Hazards
Excerpt from ERG Guide 128 [Flammable Liquids (Water-Immiscible)]:
CAUTION: Petroleum crude oil (UN1267) may contain TOXIC hydrogen sulphide gas.
DOT ID and Guide2461 128
Reactive GroupHydrocarbons, Aliphatic Unsaturated
Reactivity AlertsHighly Flammable
Reactivity Profile
METHYLPENTADIENE may react vigorously with strong oxidizing agents. May react exothermically with reducing agents to release hydrogen gas. In the presence of various catalysts (such as acids) or initiators, may undergo exothermic addition polymerization reactions. May undergo autoxidation upon exposure to the air to form explosive peroxides. Violent explosions at low temperatures in ammonia synthesis units have been traced to the addition products of dienes and nitrogen dioxide [Bretherick, 5th Ed., 1995].
Air and Water ReactionsHighly flammable. Insoluble in water.
