Ammonium picrate is a nitro hydrocarbon derivative. It is composed of yellow crystals with not less than 10% water by mass. Ammonium picrate is highly explosive when dry and a flammable solid when wet, and is slightly soluble in water. The four-digit UN identification number for ammonium picrate with not less than 10% water is 1310. The primary uses are in pyrotechnics and explosives.
Ammonium picrate is a bright yellow crystalline
solid, which turns red if contaminated.
In explosives, fireworks, rocket propellants.
A yellow crystalline solid. Produces toxic oxides of nitrogen during decomposition . Easily ignited and burns vigorously. May explode under prolonged exposure to fire or heat. The primary hazard is the blast effect of instantaneous explosion and not from flying projectiles and fragments.
AMMONIUM PICRATE is a high explosive when dry [Hawley]. Mixing with water greatly reduces its sensitivity to shock, friction and heat. Traces of metallic picrates may significantly lower the temperature at which this mixture will explode (Military Explosives p. 96). Self-reactive.
A high explosive when dry, flammable
when wet.
Fire may produce irritating, corrosive and/or toxic gases.
MAY EXPLODE AND THROW FRAGMENTS 1600 meters (1 MILE) OR MORE IF FIRE REACHES CARGO.
An allergen. Moderately
irritating to skin, eyes, and mucous
membranes. Moderately flammable by
spontaneous chemical reaction. A powerful
oxidizer that reacts vigorously with reducing
materials. Dangerous explosive when
shocked or heated. The presence of trace metals increases its heat sensitivity. See
PICRIC ACID, NITRATES, and
EXPLOSIVES, HIGH. When heated to
decomposition it emits highly toxic fumes of
NOx.
Used in explosives, fireworks and
rocket propellants.

heated or shocked.
Keep away from metals, sodium nitrite, perchlorates, peroxides,
permanganates, and any form of shock.
