Dichlorodiphenyltrichloroethane, commonly known as DDT, is a colorless, tasteless, and almost odorless crystalline chemical compound, [5] an organochloride. Originally developed as an insecticide, it became infamous for its environmental impacts. DDT was first synthesized in 1874 by the Austrian chemist Othmar Zeidler.

2025年3月6日 · DDT (dichloro-diphenyl-trichloroethane) was developed as the first of the modern synthetic insecticides in the 1940s. It was initially used with great effect to combat malaria, typhus, and the other insect-borne human diseases among both military and civilian populations.

Dichlorodiphenyl-trichloroacetic acid (or DDT) is a chlorinated hydrocarbon that has been widely used as an insecticide. DDT is virtually insoluble in water , but is freely soluble in oils and in the fat of organisms. DDT is also persistent in the environment.
