General Description
Crystals or off-white powder.
Reactivity Profile
4,4'-DICHLORODIPHENYL SULFONE(80-07-9) is incompatible with strong oxidizers.
Air & Water Reactions
Insoluble in water.
Fire Hazard
Flash point data for this chemical are not available; however, 4,4'-DICHLORODIPHENYL SULFONE is probably combustible.
Chemical Properties
off-white crystals or powder
Uses
4,4’Dichlorodiphenyl Sulfone is an impurity of Dapson (D193250), an antibacterial used in the treatment of dermatitis herpetiformis.
Health effects
4,4'-Dichlorodiphenyl sulfone (DCDPS) is not expected to be irritating to the eyes and skin and is not expected to be sensitizing. Accidentally swallowing DCDPS one time in a small amount is not likely to cause injury. However, swallowing DCDPS repeatedly over a long period of time, has been shown to cause effects on the liver in animals. DCDPS is not considered a carcinogen (cancer-causing). DCDPS does not have a toxic effect on fertility or a developing child.
Flammability and Explosibility
Nonflammable
Safety Profile
Mildly toxic by ingestion. When heated to decomposition it emitsvery toxic fumes of Cl- and SOx.
Environmental Fate
4,4'-Dichlorodiphenyl sulfone (DCDPS) is not sold to the general public. The chemical has properties indicating it may be a hazard to the environment. DCDPS is consumed during the formation of the polymer, which means that it is unlikely that there is any unreacted or free DCDPS in final consumer products. DCDPS is considered stable in water (will not degrade in water). DCDPS has been experimentally demonstrated to be not readily biodegradable in soil and sediment (activated sludge). This means it is not easily broken down by bacteria or enzymes in soil and sediment.
