The metabolism ofo-fluoroaniline by rats, rabbits and marmosets

Abstract

1. o-Fluroaniline is rapidly metabolized and excreted in rats, rabbits and marmosets. Following a single oral dose of ¹⁴C-fluoroaniline of about 20 mg/kg, more than 80% of the dose is excreted in 0–24 h, the urine being the major route of excretion for all three species. 2. For all three species, 4-amino-3-fluorophenol is a major metabolite, conjugated at oxygen with either sulphate or glucuronic acid. 4-Acetylamino-3-fluorophenyl sulphate or glucuronide are also significant metabolites. 3. An h.p.l.c. method with electrochemical detection was developed for monitoring exposure of plant workers to o-fluoroaniline, based on 4-amino-3-fluorophenyl sulphate.
