Description

Milbemycin is a potent macrocyclic lactone compound belonging to the milbemycin family, widely recognized for its exceptional anthelmintic and insecticidal properties. Its primary value lies in its high efficacy and broad-spectrum activity against a wide range of parasites, making it a cornerstone in veterinary and agricultural pest management. This product is essential for manufacturers in the animal health sector formulating endectocides, as well as for agricultural companies developing advanced crop protection solutions.

Application

• Active Pharmaceutical Ingredient (API) in veterinary anthelmintic formulations for livestock, pets, and companion animals.
• Key intermediate in the synthesis of commercial acaricides and insecticides for agricultural use.
• Critical component in the production of parasiticides for controlling internal and external parasites in animals.
• Research and development of novel pest control agents in the agrochemical industry.
• Manufacturing of pour-on, injectable, and oral formulations for veterinary medicine.
• Use in integrated pest management (IPM) programs due to its specific mode of action.

Quality Control

Our Milbemycin is produced under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for assay and related substances, to meet stringent in-house specifications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect stability and potency.
