Epi-Ivermectin B1a is a base-catalysed intermediate in the decomposition of Ivermectin. Epi-Ivermectin B1a is formed by epimerisation at the 2-position which ultimately rearranges irreversibly to the isomeric alkene analog, Δ 2 -ivermectin B1a. Despite the importance of Ivermectin as an anthelmintic in animal health, there are no published reports of the biological activity or the levels of Epi-Ivermectin B1a in animals or the environment.
Epi-Ivermectin B1a is soluble in ethanol, methanol, DMF or DMSO.
