Its esters, particularly the ethyl ester (flufenpyr-ethyl), are used as contact herbicides for the control of broad-leaved weeds. It has a role as a herbicide and an EC 1.3.3.4 (protoporphyrinogen oxidase) inhibitor. It is a monocarboxylic acid, an aromatic ether, a pyridazinone, a member of monofluorobenzenes and a member of monochlorobenzenes."}]
