ChEBI: Dicamba-sodium is an organic sodium salt of dicamba. It has a role as a herbicide and an agrochemical. It contains a 3,6-dichloro-2-methoxybenzoate.
The industrial manufacture of dicamba-sodium follows the same broad pattern used for other amine salts of phenoxy- and benzoic-acid herbicides: first produce purified dicamba acid, then convert it into the desired amine salt under tightly controlled neutralisation conditions. The upstream steps mirror standard dicamba production, constructing the dimethyl-chlorobenzoic acid core through halogenation and methylation chemistry, followed by carboxylation and purification to yield technical-grade dicamba acid. To form the sodium salt, this acid is dissolved or slurried in a suitable medium and treated with a sodium base, typically sodium hydroxide, at a defined pH and temperature to ensure complete salt formation without leaving excess base or unreacted acid.
A carboxylic acid salt. Dicamba sodium salt will behave as a weak base.
Selective, systemic, absorbed through leaves and translocates throughout plant. Synthetic auxin.
