Definition
ChEBI: A sulfone that is diphenylsulfone in which the hydrogen atom at the 4 position of each of the phenyl groups is substituted by an amino group. It is active against a wide range of bacteria, but is mainly employed for its actions against Mycobacteriu leprae, being used as part of multidrug regimens in the treatment of all forms of leprosy.
General Description
Odorless white or creamy white crystalline powder. Slightly bitter taste.
Air & Water Reactions
Sensitive to oxidation and light. Insoluble in water.
Reactivity Profile
4,4'-Diaminodiphenylsulfone can neutralize acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated in combination with strong reducing agents, such as hydrides. Incompatible with strong oxidizing agents. Also incompatible with epoxy resins under uncontrolled conditions .
