Fluazifop-P-butyl is a post-emergence herbicide used to control grass weeds in a range of cropping situations. It has a low aqueous solubility, miscible in many organic solvents and is not considered to be volatile. It is not expected to be persistent in either soil or water-sediment systems. It is unlikely to leach to groundwater. Toxicity to biodiversity is low to moderate. Fluazifop-P-butyl also has a low oral mammalian toxicity.
Pale yellow liquid. Odorless.
Fluazifop-P-butyl may be used as a reference standard for the determination of the analyte:
- In different varieties of lettuce (Lactuca sativum) by capillary gas chromatography with nitrogen–phosphorus detection (NPD).
- In tea samples by modified QuEChERS (quick, easy, cheap, effective, rugged, and safe) sample preparation procedure combined with ultra-performance liquid chromatography-electrospray tandem mass spectrometry (UPLC/MS/MS).

ChEBI: A butyl 2-(4-{[5-(trifluoromethyl)pyridin-2-yl]oxy}phenoxy)propanoate that has R configutation. The active enantiomer of the herbicide fluazifop-butyl, it is used as a post-emergence herbicide for the control grass weeds in various broad-l
aved crops.
The commercial production of fluazifop-P-butyl involves a stereoselective synthesis to isolate the herbicidally active R-enantiomer of fluazifop-butyl. The process begins with the preparation of a substituted pyridyl ether intermediate, typically involving the reaction of 5-(trifluoromethyl)-2-pyridinol with a halogenated phenol to form the aryloxyphenoxy core. This intermediate is then coupled with (R)-2-chloropropionic acid or its derivatives under controlled conditions to ensure retention of stereochemistry. The resulting acid is esterified with butanol to produce the butyl ester form, fluazifop-P-butyl. Purification steps such as crystallisation or chromatography are used to isolate the pure R-isomer, which is then formulated.
Selective, absorbed through leaf surface. Acetyl CoA carboxylase inhibitor (ACCase) - distrupts fatty acid biosynthesis and lipid formation.
Fluazifop-butyl is a selective post emergence aryloxyphenoxypropionate/organofluorine herbi cide. Its principal uses In California is on rights-of-way,
landscapes, almonds, cotton, and outdoor container
nurseries.
