SILVEX METHYL ESTER Chemical Properties,Uses,Production

Uses

2,4,5-TP methyl ester

Production Methods

Fenoprop-methyl 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 esterified with methanol under controlled, typically acid-catalysed conditions, using heat and continuous removal of water to drive the equilibrium toward the methyl ester while avoiding degradation of the phenoxy structure.

Mechanism of action

Synthetic auxin affecting nucleic acid biosynthesis and cell elongation. Systemic, selective.

Pesticide Type

Herbicide; Plant Growth Regulator
