As a a diphenyl ether herbicide, Oxyfluorfen is a white to orange or red-brown crystalline solid with a smoke-like odor, which is used for broad-spectrum pre- and post-emergent control of annual broadleaf and grassy weeds in a variety of tree fruit, vegetables, fruit, cotton, nut, vine, and field crops. It belongs to the contact herbicide and requires light to impose killing effects on target plants. Besides, it can also be applied in non-agricultural ornamental and forestry, mainly used for weed control in landscapes, patios, driveways, and similar areas in residential sites.

Oxyfluorfen is a semi-solid at room temperature, red-brown to
yellow, faint smoky odor.
Orange to deep redbrown crystalline solid
or powder. Smoke-like odor.
Oxyfluorfen is a diphenyl ether broad spectrum herbicide. Oxyfluorfen is a pre- and post-emergent control broad leaf and grassy weeds in field crops.
ChEBI: Oxyfluorfen is an aromatic ether. It has a role as a herbicide and an EC 1.3.3.4 (protoporphyrinogen oxidase) inhibitor.
The industrial synthesis of oxyfluorfen begins with a key reaction between resorcinol and 3,4-dichlorobenzotrifluoride. This step forms the ether linkage between the aromatic rings. The intermediate is then nitrated to introduce the nitro group, enhancing herbicidal activity. Subsequently, the compound is treated with ethanol in the presence of a base catalyst such as potassium hydroxide, which facilitates the ethoxylation of the phenol ring. These reactions are typically carried out in organic solvents under controlled temperature and pressure to ensure high yield and purity.
Orange crystalline solid. Non corrosive. Used as an herbicide.
A trifluoromethyl diphenyl ether derivative.
Herbicide: Oxyfluorfen is used for broad-spectrum pre-emergence
and post-emergent control of annual broadleaf and
grassy weeds in a variety of tree fruit, nut, vine, and field
crops. The largest agricultural markets are wine grapes
and almonds. Also used on ornamental and forestry sites.
Oxyfluorfen is also used for weed control in landscapes,
patios, driveways, and similar non-crop areas in residential,
highway and rights-of-way sites. Not approved for use in
EU countries. Registered for use in the U.S. and Canada

Selective with contact action. Inhibits protoporphyrinogen oxidase, leading to irreversible cell membrane damage.
When heated to decomposition emits toxic fumes of Cl-, F-, and NO2.
