Famphur oxon

Seventeen organophosphate pesticides (e.g., famphur and famphur oxon, para-oxon, fenthoxon, ronnel, 3-chloro-4-methyl-7-hydroxycoumarin, stitofos, parathion, coumaphos) were extracted from beef tissues and baseline resolved on a C g colunm (photodiode array detector, A = 190-350 nm). A complex 34-min 55/45 - 70/30 acetonitrile/water gradient was used [957]. Excellent peak shapes were obtained. A... 

Famoxon is about 100 times more effective than famphur in controlling houseflies (Musca spp.), which confirms the generalization that the corresponding oxons are the most effective anticholinesterase agents and are, in fact, the actual toxicants (O Brien et al. 1965).
