Five metabolites were detected in the plasma and urine of a patient following ingestion of the organophosphate insecticide, phenthoate. Intact phenthoate was detected only in gastric lavage fluid. After methylation of acidic extracts of plasma and urine, phenthoate acid, demethyl phenthoate, demethyl phenthoate oxon acid, demethyl phenthoate S-isomer, and demethyl phenthoate acid S-isomer were identified with synthesized phenthoate analogues by gas chromatography and gas chromatograph-mass spectrometry. The main metabolites were phenthoate acid and demethyl phenthoate oxon acid. Although demethyl phenthoate oxon acid was a significant metabolite, no phenthoate oxon, phenthoate oxon acid or demethyl phenthoate oxon were detected. If the oxon was formed in the patient, it may have been rapidly degraded by carboxylesterase or glutathione transferase to demethyl phenthoate oxon acid.
