2,4-D-Methyl ester Chemical Properties, Uses, Production

Uses

2,4-D methyl ester

Production Methods

Commercial production of 2,4-D-methyl would have followed the same industrial pathway used for other ester derivatives of 2,4-D, although specific data for this variant are limited. Production begins with large scale synthesis of 2,4-D acid, after which the acid is esterified with methanol under controlled temperature and solvent conditions to form the methyl ester.

Mechanism of action

Selective, systemic, absorbed through roots and increases biosynthesis and production of ethylene causing uncontrolled cell division and so damages vascular tissue. Synthetic auxin.

Purification Methods

Crystallise the herbicide ester from MeOH. [Branch & Jones J Chem Soc 2924 1955, Beilstein 6 III 705, 6 IV 909.]
