What is Diazodinitrophenol?

Plain description, key identifiers and synonyms

Diazodinitrophenol appears as a yellow crystalline solid that darkens on exposure to sunlight. Must be shipped wet with at least 40% water or water and denatured alcohol mixture. May explode due to shock, heat, flame, or friction if dry. May explode under prolonged exposure to heat or fire. Primary hazard is blast of an instantaneous explosion, not flying projectiles or fragments.
