Abstract

For the elucidation of the distribution and biotransformation of Cyfluthrin in tse‐tse flies the tritium‐labelled compound was needed. A brominated precursor was dehalogenated with tritium gas using a special noble metal catalyst to give the desired [^3^H]Cyfluthrin. The labelling position was confirmed by ^3^H‐NMR spectroscopy. After synthesis and purification, the [^3^H]Cyfluthrin obtained showed a specific activity of 23.7 Ci/ mmol (877 GBq/mmol).

A GC-MS method capable of completely separating the four pairs of diastereoisomers of cyfluthrin is presented and the method used to show that isomerisation of the cyfluthrin enantiomers occurs in methanol. This methanolinduced isomerisation could also be demonstrated by bioassays using water fleas.
