Description

Oxytetracycline Hydrochloride is a broad-spectrum antibiotic belonging to the tetracycline class, widely recognized for its efficacy against a range of Gram-positive and Gram-negative bacteria, as well as certain other microorganisms. Its primary commercial value lies in its critical role in veterinary medicine, aquaculture, and as a feed additive to promote growth and prevent disease. This makes it an essential raw material for manufacturers in the animal health, pharmaceutical, and agricultural sectors seeking reliable, high-quality antibiotic inputs.

Application

• Veterinary Pharmaceuticals: A key active ingredient in injectable solutions, powders, and ointments for treating bacterial infections in livestock, poultry, and companion animals.
• Aquaculture & Fish Farming: Used in medicated feeds and baths to control bacterial diseases such as furunculosis in salmon and vibriosis in shrimp.
• Animal Feed Additive: Incorporated at sub-therapeutic levels to improve feed efficiency, promote growth, and maintain herd health in food-producing animals.
• Agricultural Uses: Applied for the control of certain bacterial plant pathogens, such as fire blight in pome fruits.
• API Manufacturing: Serves as a critical Active Pharmaceutical Ingredient (API) for formulators producing finished antibiotic dosage forms.
• Research & Development: Utilized in microbiological laboratories as a standard antibiotic in culture media and for studying bacterial resistance mechanisms.
