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.
hydrazine sulfate was suspended in hot water, potassium acetate was added, boiled and cooled, ethanol was added, and the solid was filtered off and washed with ethanol to obtain a filtrate. 2,4-= nitrobenzene ethanol was added to the above hydrazine solution, filtered, washed, dried, and the filtrate was concentrated to give 2,4-= nitrophenylhydrazine.
color reagent for the determination of aldehydes and ketones by thin layer chromatography. It is used as an ultraviolet derivative reagent for aldehydes and ketones, and is used in organic synthesis and explosive manufacturing.
rat oral LDso:654mg/kg. It is irritating to eyes and skin. Sensitizing to the skin. This product is absorbed into the body, can cause methemoglobinemia, cyanosis. Store in a cool, ventilated warehouse. Keep away from fire and heat source. The bin temperature should not exceed 30 ℃. Protection from direct sunlight. Keep the container sealed. For safety reasons, it is frequently moistened and passivated with not less than 25% water during storage and transportation. Should be stored separately from oxidants and acids. Mixed storage and transportation should not be avoided.
