Cyromazine is a triazine insect growth regulator used as an insecticide and acaricide. It is an aminotriazine cyclopropyl derivative of melamine. Cycromazine undergoes hydrolysis at extreme pH or photodegradation leading to the stable heterocyclic structure melamine. It can be metabolized in plants and animals and undergoes degradation in the environment to form melamin. In veterinary research, Cyromazine is used as an ectoparasiticide. It has activity against dipterans and some other insects. It is also used for food safety as Cyromazine and its metabolite melamine can appear as residues in milk. It is a candidate for disease vector control and management of insecticide resistance due to absence of cross-resistance with common insecticides.
Cyromazine is soluble in DMSO and methanol.
