2,4-Dinitrophenylhydrazine - Nature
Open Data Verified Data
red crystalline powder. The melting point was about 200 °c. Slightly soluble in water, ethanol, soluble in acid. When heated, exposed to open flame, high heat, or subjected to friction and shock, explosion can occur. Toxic, irritating smoke is emitted during combustion. Mixing with an oxidizing agent can form an explosive mixture.
