Fenbendazole

Methyl 5-(phenylthio)-2-benzimidazolecarbamate · CAS 43210-67-9

Veterinary USP / Veterinary grade / CP CoA per batchSDSMRL guidance note

A benzimidazole anthelmintic with a wide margin and a long withdrawal period, which is why the MRL guidance matters as much as the CoA. Supplied micronised because suspension stability depends on it.

Part of the veterinary antiparasitic line. Most of these are formulated as drenches or premixes, so particle size is specified with the product.
