Measured properties

Appearance
Sodium picramate appears as 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. · Sodium picramate, wetted with not less than 20% water appears as a slurry of dark red crystals. Highly explosive. Burns vigorously when dry. May explode if in large quantities. Burns when wet, but difficult to ignite. Produces toxic oxides of nitrogen during combustion.
