Description

Milbemycin β2 is a potent macrocyclic lactone compound belonging to the milbemycin family, a group of natural products derived from fermentation. This specific isomer is valued for its high biological activity and serves as a crucial intermediate in the synthesis of advanced agrochemical and pharmaceutical agents. It is primarily sought by manufacturers in the animal health, crop protection, and pharmaceutical research sectors for developing next-generation parasiticides and acaricides.

Application

• Agrochemical Intermediate: A key building block for the synthesis of novel, high-efficacy miticides and insecticides used in crop protection.
• Veterinary Pharmaceutical Active: Used in the production of endectocides for the control of internal and external parasites in livestock and companion animals.
• Research & Development: Serves as a reference standard and starting material in pharmaceutical R&D for new antiparasitic therapies.
• Technical Formulation: Incorporated into technical-grade concentrates for the manufacture of finished pesticide formulations.
• Biocide Development: Explored for use in non-agricultural biocidal products for material and surface protection.
