Description

Oxytetracycline Hydrochloride is a broad-spectrum antibiotic belonging to the tetracycline class, widely used for its potent bacteriostatic activity. Its primary value lies in its effectiveness against a wide range of Gram-positive and Gram-negative bacteria, mycoplasmas, and certain other microorganisms. This makes it a critical active pharmaceutical ingredient (API) for manufacturers in the veterinary and pharmaceutical industries, where it is formulated into various medicinal products.

Application

• Primary use as an Active Pharmaceutical Ingredient (API) in human and veterinary antibiotic formulations.
• Manufacturing of injectable solutions, oral powders, and medicated feed premixes for veterinary medicine to treat respiratory, gastrointestinal, and systemic infections in livestock and poultry.
• Key component in aquaculture treatments to control bacterial diseases in fish and shrimp.
• Used in topical ointments and creams for treating bacterial skin infections.
• Research and development applications in microbiological laboratories as a selective agent.
• Intermediate in the synthesis of other tetracycline-derived pharmaceutical compounds.

Quality Control

Our Oxytetracycline Hydrochloride is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets high-purity standards, including specifications for identity, potency, and impurity profiles. Certificates of Analysis (COA) compliant with current USP, EP, or BP monographs are provided to guarantee traceability and consistency for pharmaceutical and veterinary applications.

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 nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect stability and potency.
