PRODUCT INTRODUCTION
description
Chloridazon is 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. It has a role as an environmental contaminant, a xenobiotic and a herbicide. It is a pyridazinone, an organochlorine compound, a primary amino compound and a member of benzenes.
