Description

L-Glutamic Acid, Compound With Erythromycin (1:1) is a pharmaceutical salt formed by the combination of the amino acid L-glutamic acid and the macrolide antibiotic erythromycin. This specific 1:1 molecular complex is engineered to enhance the stability, solubility, or bioavailability profile of the active pharmaceutical ingredient. It is a critical intermediate or active component primarily for the development and manufacturing of specialized antibiotic formulations. Target industries include pharmaceutical synthesis, veterinary medicine, and advanced research into antimicrobial agents.

Application

• Pharmaceutical Intermediate: Serves as a key starting material or active component in the synthesis of advanced antibiotic drugs.
• Veterinary Pharmaceuticals: Used in formulating treatments for bacterial infections in livestock and companion animals.
• Antimicrobial Research: Employed in R&D for studying modified erythromycin derivatives with improved pharmacological properties.
• Drug Delivery Systems: Utilized in developing formulations aimed at enhancing drug stability and controlled release.
• Reference Standard: Acts as a certified reference material for quality control and analytical testing in regulatory compliance.

Quality Control

Our L-Glutamic Acid, Compound With Erythromycin (1:1) is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including identification, assay, and impurity profiling, to ensure it meets high-purity standards suitable for pharmaceutical applications. A Certificate of Analysis (COA) detailing specific results for purity, related substances, and residual solvents is provided with every shipment to guarantee traceability and compliance with your specifications.

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 opening to prevent degradation from atmospheric moisture. Keep away from incompatible materials.
