Description

Hydroxytetracycline is a broad-spectrum antibiotic belonging to the tetracycline class, distinguished by its hydroxyl group modification. This compound is valued for its efficacy against a wide range of Gram-positive and Gram-negative bacteria, mycoplasmas, and certain protozoa. It is a critical active pharmaceutical ingredient (API) and intermediate for manufacturers in the pharmaceutical, veterinary medicine, and aquaculture industries seeking reliable antimicrobial solutions.

Application

• Pharmaceutical API: Serves as a key active ingredient in the formulation of human and veterinary antibiotic preparations.
• Veterinary Medicine: Used in medicated feeds, injectables, and topical treatments for livestock, poultry, and companion animals.
• Aquaculture: Applied in fish and shrimp farming to prevent and treat bacterial diseases.
• Research & Development: Utilized as a standard or intermediate in microbiological research and the development of new therapeutic agents.
• Feed Additive: Incorporated at sub-therapeutic levels to promote growth and improve feed efficiency in animal production.

Quality Control

Our Hydroxytetracycline is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets stringent specifications for pharmaceutical and industrial use. Certificates of Analysis (COA) documenting purity, related substances, and residual solvents are available upon request to support your quality assurance protocols.

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). This product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed and away from direct light and moisture to maintain stability and potency.
