Ivermectin

22,23-Dihydroavermectin B1a/B1b, IVM · CAS 70288-86-7

Veterinary USP / EP / Veterinary grade CoA per batchSDSUSDMF Type IVB1a/B1b ratio statement

Ivermectin is a fermentation-derived mixture, and the B1a:B1b ratio is the parameter that separates a compliant lot from a cheap one. We report the ratio and the total avermectin content per batch, not just a single assay figure.

Cost per kilogramme is high and dose rates are low, so buyers are sensitive to moisture pickup in small packs. Foil-laminated sachets with desiccant are our default for the 1 kg presentation.
