Description

Chlortetracycline is a broad-spectrum antibiotic belonging to the tetracycline class, recognized for its potent bacteriostatic activity. It is a critical active pharmaceutical ingredient (API) valued for its efficacy against a wide range of Gram-positive and Gram-negative bacteria, as well as other microorganisms. This compound is essential for manufacturers in the pharmaceutical, veterinary medicine, and animal feed additive industries, where it is used to formulate therapeutic and prophylactic treatments.

Application

• Primary Active Pharmaceutical Ingredient (API) in human and veterinary antibiotic formulations.
• Growth promoter and therapeutic agent in animal feed for poultry, swine, and cattle.
• Key component in medicated premixes for the prevention and treatment of bacterial infections in livestock.
• Used in topical ointments and creams for treating skin infections in animals.
• Research and development applications in microbiology and pharmaceutical studies.
• Starting material for the synthesis of other tetracycline derivatives.

Quality Control

Our Chlortetracycline is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets high-purity standards suitable for pharmaceutical and feed-grade applications. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed after opening to minimize exposure to atmospheric moisture and light, which can degrade the product.
