MSDS Information
Chloridazon Usage And Synthesis
Chemical PropertiesBrown Solid
UsesHerbicide, active by perturbing cell membranes
DefinitionChEBI: A pyridazinone that is pyridazin-3(2H)-one substituted by an amino group at position 5, a chloro group at position 4 and a phenyl group at position 2.
Safety ProfileModerately toxic by ingestion and intraperitoneal routes. A severe eye irritant. Experimental reproductive effects. Used as a preemergence and early post-emergence herbicide. When heated to decomposition it emits very toxic fumes of Cland NOx.
