white crystalline powder | [Definition]
ChEBI: A chlorophenylethylene that is ethylene substituted by two 4-chlorophenyl groups at position 1 and two chlorine atoms at position 2. | [General Description]
White crystalline solid or white powder. | [Air & Water Reactions]
Insoluble in water. | [Reactivity Profile]
4,4'-DDE is sensitive to exposure to light. 4,4'-DDE is incompatible with strong oxidizing agents and strong bases. Oxidation is catalyzed by UV radiation. | [Fire Hazard]
Flash point data for 4,4'-DDE are not available. 4,4'-DDE is probably combustible. | [Uses]
1,1-Dichloro-2,2-bis(4-chlorophenyl)ethane(DDE) has been used to study the ability of Pseudomonas acidovorans M3GY to transform DDE and its unchlorinated analog, 1,1-diphenylethylene (DPE).It has been used to investigate the role of incubation time, solvent type, yeast inoculum growth stage and concentration on the results of yeast assay for estrogenic compounds. | [Uses]
Military product; chemical research. Degradation product of p,p′-DDT. | [Health Hazard]
A derivative of DDT; structurally and toxicproperties are similar to those of DDT;however, the acute effects are somewhatmilder; moderately toxic by ingestion; ateratogenic substance; adequate evidence ofcarcinogenicity in experimental animals
LD50 oral (rat): 880 mg/kg
LD50 oral (mouse): 700 mg/kg. | [Safety Profile]
Suspected carcinogen withexperimental carcinogenic and neoplastigenic data. Poisonby ingestion. Experimental reproductive effects. Mutationdata reported. An insecticide. When heated todecomposition it emits very toxic fumes of Cl-. | [Source]
Agricultural runoff degradation of p,p′-DDT (quoted, Verschueren, 1983). | [Environmental Fate]
Biological. In four successive 7-day incubation periods, p,p′-DDE (5 and 10 mg/L) was recalcitrant to degradation in a settled domestic wastewater inoculum (Tabak et al.,1981).
Photolytic. When an aqueous solution of p,p′-DDE (0.004uM) in natural water samples
collected from California and Hawaii was irradiated (maximum λ= 240 nm) for 120
hours, 62% was photooxidized to p,p′-dichlorobenzophenone (Ross and Crosby, 1985).
When p,p′-DDE in water was irradiated at 313 nm, a quantum yield of 0.3 was
achieved. A photolysis half-life of 0.9 days in summer and 6.1 days in winter by direct
sunlight at 40° latitude was observed. Photolysis products included DDMU (yield 20%),
o-chl
When p,p′-DDE in a methanol solvent was photolyzed at 260 nm, a dichloro-benzophenone,
a dichlorobiphenyl, DDMU and 3,6-dichlorofluorenone (yield 10%) formed
as the major products (Plimmer et al., 1970).
Chemical/Physical. May degrade to bis(chlorophenyl)acetic acid (DDA) and hydrochloric
acid in water (Verschueren, 1983) or oxidize to p,p′-dichlorobenzophenone using
UV light as a catalyst (U.S. Department of Health and Human Services, 1989). | [Purification Methods]
Crystallise DDE from MeOH or EtOH and dry it in vacuo. The purity is checked by TLC. [G.tzi & Stammbach Helv Chim Acta 28 569 1946, Beilstein 5 H 639, 5 III1891.] POSSIBLE CARCINOGEN. | [Toxics Screening Level]
The Initial Risk Screening Level (IRSL) for p,p'-DDE is 0.01 μg/m3 based on an annual averaging time. |
