[Production Methods]

Commercial manufacture of MCPA-potassium typically begins with the chlorination of para-cresol to form 4-chloro-2-methylphenol, which is then carboxylated, most commonly via the Kolbe–Schmitt process, to yield the acid MCPA. The crude acid is purified and neutralised with potassium hydroxide in aqueous solution, producing the water-soluble poassium salt.
[Mechanism of action]

Selective, systemic with translocation. Synthetic auxin.
