What is Captan?

Plain description, key identifiers and synonyms

Captan is a dicarboximide that is 3a,4,7,7a-tetrahydrophthalimide in which the hydrogen attached to the nitrogen is replaced by a trichloromethyl group. A non-systemic fungicide introduced in the 1950s, it is widely used for the control of fungal diseases in fruits, vegetables, and ornamental crops. It has a role as an antifungal agrochemical. It is a member of isoindoles, an organosulfur compound, an organochlorine compound and a phthalimide fungicide.
