Description

Teicoplanin A2-4 is a potent glycopeptide antibiotic complex, primarily composed of the A2-4 components, with the CAS registry number 91032-37-0. It is valued for its strong bactericidal activity against Gram-positive bacteria, including methicillin-resistant strains. This makes it a critical active pharmaceutical ingredient (API) for the development and formulation of advanced anti-infective therapies. Key industries requiring this high-purity compound include pharmaceutical manufacturing, clinical research, and biotechnology.

Application

• Pharmaceutical API: Serves as the core active ingredient in injectable antibiotic formulations for serious systemic infections.
• Research & Development: Used in microbiological studies, mechanism of action research, and the development of new antibiotic derivatives or combination therapies.
• Reference Standard: Employed as a high-purity analytical standard in quality control laboratories for HPLC, LC-MS, or microbiological assay calibration.
• Veterinary Medicine: Potential application in developing treatments for bacterial infections in animals.
• Microbiological Media: Can be incorporated into selective culture media for the isolation of specific bacterial strains in diagnostic settings.

Quality Control

Our Teicoplanin A2-4 is manufactured and tested under strict quality management systems. Each batch is analyzed to meet high-purity standards suitable for pharmaceutical research and development. Comprehensive testing includes identity confirmation, potency assay, and impurity profiling. A Certificate of Analysis (COA) detailing all specifications and test results is provided with every shipment to ensure full traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider desiccants or inert atmosphere.
