[Definition]

ChEBI: Disul is an aromatic ether. It has a role as a phenoxy herbicide.
[Production Methods]

Commercial manufacture of disul was historically tied to its role as a precursor in the synthesis of the herbicide 2,4 D. Industrial production involved reacting 2,4 dichlorophenoxyethanol with sulfuric acid to form the corresponding hydrogen sulphate ester, yielding disul as a solid intermediate suitable for formulation or further conversion.
[Mechanism of action]

Not itself phytotoxic but is rapidly converted to 2,4-D which is synthetic auxin
