Description

Erythromycin Carbonate CAS NO 54579-17-8 is a macrolide antibiotic salt, specifically the carbonate ester derivative of erythromycin. This compound is valued for its enhanced stability and solubility profile compared to the base form, making it a crucial intermediate in advanced pharmaceutical manufacturing. It is primarily required by producers of veterinary medicines, human pharmaceutical formulations, and manufacturers of medicated animal feed additives.

Application

• Key intermediate in the synthesis of advanced macrolide antibiotic formulations.
• Active pharmaceutical ingredient (API) for veterinary injectable and oral solutions.
• Manufacture of medicated premixes for growth promotion and disease prevention in livestock and poultry.
• Production of topical ointments and creams for bacterial skin infections in animals.
• Research and development of novel antibiotic derivatives and prodrugs.
• Component in the preparation of long-acting, sustained-release antibiotic formulations.

Quality Control

Our Erythromycin Carbonate is produced under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets high-purity standards suitable for pharmaceutical and veterinary use. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request to support your regulatory and quality assurance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect stability and potency.
