Abstract: The present invention provides uses of aryl alkyl malononitrile compounds of formula (I), or veterinarily acceptable salts thereof, for controlling and preventing parasite infestations in animals. The invention also provides methods for controlling and preventing parasite infestation in animals comprising administering an effective amount of at least one aryl alkyl malononitrile compound of formulae (I), or a veterinarily acceptable salt thereof, to the animal.

Abstract: Provided herein is a process for preparing a pyridazine amine compound of formula V, and a process for preparing dichloropyridazine amine compounds of formula IVa, IVb, and mixtures thereof. Further, provided herein are novel dichloropyridazine amine compounds of formula IVa, IVb, and mixtures thereof, wherein the amino group is an ethylamino group.
