Diethylstilbestrol Diphosphate USP (Stilphostrol) is used to treat Prostatic carcinoma.

General Description

Odorless off-white crystalline powder.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

Organophosphates, such as FOSFESTROL, are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides.

Fire Hazard

Flash point data for FOSFESTROL are not available; however, FOSFESTROL is probably combustible.
