Bispyribac-sodium Usage And Synthesis

Uses

Bispyribac is used as a herbicide for the prevention and control of weeds.

Definition

ChEBI: Bispyribac-sodium is the organic sodium salt of bispyribac. It is used as a broad spectrum post-emergent herbicide for the control of grasses, sedges and broadleaf weeds in rice crops. It has a role as a herbicide, an agrochemical and an environmental contaminant. It contains a bispyribac(1-).

Metabolic pathway

More than 90% of the radioactivity is excreted in rat urine 96 h after the rats are orally administered 14C- bispyribac sodium. Most of the radioactivity detected in the urine, feces, liver, and plasma consists of unchanged bispyribac sodium. The metabolites identified are derived from hydroxylation on the pyrimidine ring, O-demethylation, cleavage of the ether linkage between pyrimidine and phenyl rings yielding 5-hydroxylated and mono-O-desmethylbispyribac acids, and salicylic acid and 2-pyrimidinole derivatives.
