Description

Moxidectin CAS NO 119718-45-5 is a potent semi-synthetic macrocyclic lactone belonging to the milbemycin class of compounds. It is valued for its high efficacy and broad-spectrum activity against internal and external parasites. This active pharmaceutical ingredient (API) is essential for manufacturers in the animal health and veterinary pharmaceutical industries, serving as a key component in formulations for livestock, companion animals, and aquaculture.

Application

• Primary active ingredient in veterinary endectocide formulations for cattle, sheep, and horses.
• Key component in topical and injectable solutions for the treatment and prevention of heartworm (Dirofilaria immitis) in dogs and cats.
• Used in parasitic control products for companion animals, targeting mites, ticks, and lice.
• Formulated into pour-on solutions for livestock to control gastrointestinal nematodes and ectoparasites.
• Research and development of novel antiparasitic agents in human and veterinary medicine.
• Manufacturing of long-acting injectable formulations for sustained parasite control.
• Production of medicated feeds and supplements for aquaculture and livestock.

Quality Control

Our Moxidectin is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets high-purity standards suitable for pharmaceutical applications. A comprehensive Certificate of Analysis (COA) is provided with every shipment, detailing parameters such as assay, related substances, and residual solvents. We support compliance with cGMP and relevant veterinary pharmacopoeia guidelines.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to minimize exposure to moisture. Keep away from incompatible materials.
