Description

Oxytetracyclinehydrochloride CAS NO 2658-46-0 is the hydrochloride salt form of oxytetracycline, a broad-spectrum antibiotic belonging to the tetracycline class. This compound is valued for its potent antibacterial activity against a wide range of Gram-positive and Gram-negative organisms. It is a critical active pharmaceutical ingredient (API) primarily required by the pharmaceutical and veterinary medicine industries for the formulation of therapeutic treatments.

Application

• Pharmaceutical API: Used as the active ingredient in human and veterinary antibiotic formulations, including tablets, capsules, and injectables.
• Veterinary Medicine: Key component in treatments for bacterial infections in livestock, poultry, aquaculture, and companion animals.
• Aquaculture: Employed to control and treat bacterial diseases in farmed fish and shrimp.
• Feed Additive: Incorporated into animal feed at sub-therapeutic levels for growth promotion and disease prevention.
• Research & Development: Serves as a standard or reference compound in microbiological and pharmacological research.
• Topical Formulations: Used in creams and ointments for the treatment of skin infections.

Quality Control

Our Oxytetracycline Hydrochloride is manufactured under strict quality management systems. It is typically tested to meet relevant pharmacopoeial standards such as USP, EP, or BP, ensuring high purity and consistent performance. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing parameters like assay, impurity profile, and microbiological quality, which is available upon request.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture.
