Usage

Uses

Different sources of media describe the Uses of 125401-92-5 differently. You can refer to the following data:
1. Bispyribac is used as a herbicide for the prevention and control of weeds.
2. Herbicide

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.
