BUTAMIFOS Usage And Synthesis
Uses
Butamifos (S-2846) is an organophosphoramidate herbicide used to control annual weeds with low toxicity to mammals. Butamifos acts on the growing points of susceptible plants, causing severe radial enlargement of the affected tissues[1].
Definition
ChEBI: Butamifos is a C-nitro compound.
Metabolic pathway
In water, butamifos undergoes photoinduced intramolecular oxygen transfer from the nitro group to the P=?S moiety, resulting in the formation of the nitrosooxon derivative. Through the successive reduction of the nitroso group to hydroxyamino and amino groups, as well as oxidation to the nitro group, the nitrosooxon derivative is finally photodegraded to various polar compounds. The isomer of butamifos is photodegraded more slowly than butamifos in air, and its main photodegradation pathway in water is oxidation of the arylmethyl group to form a corresponding carboxylic acid derivative.
