Description

Chlortetracycline Hydrochloride is a broad-spectrum antibiotic belonging to the tetracycline class. It is valued for its potent activity against a wide range of Gram-positive and Gram-negative bacteria, mycoplasma, and certain protozoa. This makes it a critical active pharmaceutical ingredient (API) for the veterinary and animal feed industries, where it is used to promote growth and treat infections.

Application

• Veterinary Medicine: Primary use as an injectable or oral antibiotic for treating bacterial infections in livestock, poultry, and companion animals.
• Animal Feed Additive: Incorporated into feed at sub-therapeutic levels to promote growth, improve feed efficiency, and prevent disease in food-producing animals.
• Aquaculture: Used to control and treat bacterial diseases in fish and shrimp farming operations.
• Pharmaceutical Intermediates: Serves as a key starting material or intermediate in the synthesis of other tetracycline-class antibiotics and derivatives.
• Research & Development: Utilized in microbiological and biochemical research as a selective agent and for studying protein synthesis inhibition.
