Levamisole Hydrochloride

(-)-6-Phenyl-2,3,5,6-tetrahydroimidazo[2,1-b]thiazole hydrochloride · CAS 16595-80-5

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

The levo enantiomer only — the racemate is a different product and not interchangeable. Optical rotation is therefore a release test, not a formality, and it is measured on every lot.

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