Eprinomectin

Eprinomectin (CAS 123997-26-2) is a semi-synthetic macrocyclic lactone endectocide derived from the avermectin family, distinguished by the presence of a 4”-epi-acetylamino group. This structural modification enhances its safety profile and systemic persistence, making it a preferred active ingredient in veterinary parasiticides for both food-producing and companion animals. Our product is supplied as a white to off-white crystalline powder with an HPLC purity of ≥95%, meeting the requirements for formulation and R&D use.

As a potent modulator of glutamate-gated chloride channels, eprinomectin exhibits broad-spectrum activity against nematodes and arthropods. Its low milk residue levels and favorable withdrawal times have positioned it as a benchmark for parasite control in dairy cattle, where it is administered topically or by injection. The compound is also increasingly explored in combination therapies targeting resistant parasite strains.
