Amprolium HCl (CAS 137-88-2) - Quality API from Kaifeng Darui

High-Quality Amprolium Hydrochloride (CAS 137-88-2) from Kaifeng Darui: Your Trusted Veterinary API Partner

In the realm of animal health, particularly within poultry farming, the control and prevention of coccidiosis is paramount. Amprolium Hydrochloride (CAS 137-88-2) stands as a vital veterinary active pharmaceutical ingredient (API), effectively combating this parasitic disease. Kaifeng Darui Pharmaceutical Co., Ltd. is a dedicated manufacturer committed to providing high-quality Amprolium Hydrochloride to meet the diverse needs of feed mill operators, veterinary medicine manufacturers, and API distributors globally.

Understanding Amprolium Hydrochloride

Amprolium Hydrochloride is a thiamine analogue that interferes with the thiamine metabolism of coccidia parasites. By blocking the uptake of thiamine, which is essential for the parasite's growth and reproduction, Amprolium HCl effectively inhibits the development of coccidiosis in animals. Its mechanism of action targets various stages of the coccidial life cycle, making it a crucial tool in preventing and treating outbreaks.   

Applications and Target Species


The primary application of Amprolium Hydrochloride lies in the prevention and treatment of coccidiosis, a common and potentially devastating parasitic disease, particularly in poultry such as chickens and turkeys. It is widely used as a feed additive or in drinking water formulations. While its main focus is on avian species, Amprolium HCl can also be used in the management of coccidiosis in other livestock, including calves and lambs, under veterinary guidance. Its versatility makes it an indispensable component in maintaining the health and productivity of various animal populations.
