MCPB sodium is produced through a straightforward sequence that mirrors the chemistry of other phenoxy alkanoate herbicide salts. The process begins with MCPB (4 (4 chlorophenoxy)butyric acid), which is obtained by etherifying para-chlorophenol with a butyric acid derivative under alkaline conditions. Once the free acid is purified, it is neutralised with sodium hydroxide in aqueous or mixed solvent media, forming the sodium carboxylate salt.

Selective, systemic, absorbed by leaves and roots with translocation. Synthetic auxin.
