Formerly in the control of woody plants on uncropped land.
Fenoprop-butometyl was produced through a classic “ester of an ester” route that mirrored other phenoxy herbicide derivatives of its era. Manufacturers began with technical-grade fenoprop, itself obtained by chlorinating and then etherifying the appropriate phenolic precursor to install the 2-propyl side chain. Once purified, this phenoxy acid was converted into its butoxyethyl ester by reacting fenoprop’s carboxyl group with 2-butoxyethanol under standard esterification conditions, typically using an acid catalyst and controlled heating to drive off water and prevent side reactions.
