Dinitrophenol Standards and Recommendations
DOT Classification: EXPLOSIVE 1.1D; Label: EXPLOSIVE 1.1D, Poison (UN 076); DOT Class: 4.1; Label: Flammable Solid, Poison (UN 1320); DOT Class: 6.1; Label: Poison (UN 1599)
Dinitrophenol Specification
Dinitrophenol ,its cas register number is 25550-58-7. It also can be called Dinitroaminophenol ; p-Dinitrophenol ; and Phenol, dinitro- . Dinitrophenol (CAS NO.25550-58-7) serves as a slight to strong oxidizing agent and may explode in the presence of a base such as sodium hydroxide or potassium hydroxide. It is combustible though Dinitrophenol,dry or wetted with less than 15% water,by mass may require some effort to ignite. When heated, vapors may form explosive mixtures with air: indoors, outdoors and sewers explosion hazards.
