Metabolism of 14C-Labeled Hexazinone in the Rat Robert C. Rhodes* and Richard A. Jewell'
The active ingredient in Velpar weed killer is 3-cyclohexyl-6-(dimethylamino)-l-methyl-l,3,5-triazine2,4(1H,3H)-dione (hexazinone). When a rat was given a single oral dose of radiolabeled hexazinone by intragastric intubation, the radioactivity was eliminated within 72 h in the urine (61%) and feces (32%). Trace amounts of radioactivity were also found in the gastrointestinal tract (0.06%) and expired air (0.08%). No radioactivity (
