ChEBI: A 2-(4-{[5-(trifluoromethyl)pyridin-2-yl]oxy}phenoxy)propanoic acid that has R configuration. It is the active enantiomer of the herbicide fluazifop and is the major metabolite of fluazifop-P-butyl.

The production of fluazifop-P involves a multi-step organic synthesis built around constructing the aryloxyphenoxypropionic acid framework with precise stereochemistry. The process typically begins with the preparation of a substituted pyridyl ether, specifically 5-(trifluoromethyl)-2-pyridyl alcohol, which is then reacted with a halogenated phenol derivative to form the key aryloxy intermediate. This intermediate undergoes etherification with a chiral propionic acid derivative, ensuring the formation of the R-enantiomer, the biologically active form known as fluazifop-P. To enhance stability and facilitate formulation, fluazifop-P is often converted into its butyl ester (fluazifop-P-butyl), which is hydrolysed back to the acid form in plants.
