Sodium picramate Chemical Properties, Uses, Production
Chemical Properties
Dark red prescake
Uses
Manufacture of dye intermediates, organic syn- thesis.
General Description
A yellow solid. Toxic by inhalation and skin absorption. Primary hazard is fire with either a minor blast or projection hazard or both, but no mass explosion hazard. May explode under prolonged exposure to heat.
Air & Water Reactions
Flammable. Water soluble
Reactivity Profile
Sodium picramate can react vigorously with reducing agents, including hydrides, sulfides and nitrides, leading to a detonation. Emits toxic fumes when heated to decomposition.
Hazard
Dangerous fire and explosion hazard when dry. Toxic by ingestion and skin absorption.
Health Hazard
Fire may produce irritating, corrosive and/or toxic gases.
Fire Hazard
MAY EXPLODE AND THROW FRAGMENTS 1600 meters (1 MILE) OR MORE IF FIRE REACHES CARGO.
Flammability and Explosibility
Not classified
Safety Profile
Poison by ingestion. A flammable solid and explosive. When heated to decomposition it emits toxic fumes of NOx and Na2O. See also PICRAMIC ACID.
