title: Metabolism of 2-chloro-N-isopropylacetanilide (propachlor) in the rat.
abstract: Eleven urinary metabolites from [14C]propachlor were either identified or characterized by mass spectrometry. Those identified were 2-[S-(N-acetyl)cysteinyl]-N-isopropylacetanilide, 2-(methylsulfonyl)-acetanilide, 4'-hydroxy-2-(methylsulfonyl)-acetanilide, and 4'-hydroxyacetanilide. Those characterized were N-(1-hydroxyisopropyl)-2-(methylsulfonyl) acetanilide and its glucuronide, the glucuronides of 4'-hydroxy-N-isopropyl-2-(methylsulfonyl)acetanilide, N-(1-hydroxyisopropyl) aniline, 4'-hydroxy-2-(methylsulfonyl)acetanilide, and either N-(1-hydroxy-isopropyl) acetanilide or 2-hydroxy-N-isopropylacetanilide.
