| Sumario: | Trifloxystrobin is one of the main active principles belonging to the strobilurin family of crop protection compounds. In this article, the synthesis of a battery of regioisomeric functionalized derivatives of trifloxystrobin is described. The same aliphatic linear carboxylated chain was introduced as spacer arm in all of the synthesized haptens, but it was located at different positions of the parent molecule. N,N′-Disuccinimidyl carbonate was employed for hapten activation, so the resulting N-hydroxysuccinimyl ester could be readily purified and efficiently coupled to proteins. After immunization and hybridoma generation, a collection of 20 mouse monoclonal antibodies from different immunizing haptens was obtained. The analytical performance of these immunoreagents was evaluated in terms of affinity and selectivity with the aim to develop rapid and practical immunochemical procedures for trifloxystrobin determination. © 2013 Elsevier Ltd.
