[Chemical Properties]

Vap press 3 mm Hg (20C). Soluble in acetone, benzene, carbon tetrachloride, fuel oil, toluene, xylene.
[Uses]

Insecticide.
[Uses]

Isobenzan (telodrin) is a highly toxic organochloride insecticide. It was produced only in the period from 1958 to 1965 and its use has been since discontinued.[1] It is a persistent organic pollutant that can remain in soil for 2 to 7 years, and the biological half-life of isobenzan in human blood is estimated to be about 2.8 years.
[Definition]

ChEBI: Isobenzan is a member of oxolanes.
[General Description]

Crystals. The technical product is a whitish to light-brown crystalline powder with a mild chemical odor. Used as an insecticide. Not registered as a pesticide in the U.S.
[Air & Water Reactions]

Insoluble in water.
[Reactivity Profile]

Chlorine is evolved when ISOBENZAN(297-78-9) is heated above 410F. Avoid acids, certain metal salts, and catalytically active carriers. [EPA, 1998].
[Health Hazard]

ISOBENZAN is highly toxic. It is absorbed by the skin as well as by the respiratory and gastrointestinal tract. Symptoms may last for a long time because the material is eliminated slowly; its half-life in human blood is 2.77 years.
[Fire Hazard]

Chlorine is evolved when ISOBENZAN is heated above 410F. Avoid acids, certain metal salts, and catalytically active carriers.
[Safety Profile]

Poison by ingestion, skin contact,intraperitoneal, and intravenous routes. Questionablecarcinogen with experimental tumorigenic data. Used asan insecticide. When heated to decomposition it emitstoxic fumes of Clí.
