Quality Control

Our Quantamycin is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets the high-purity standards required for pharmaceutical applications. Certificates of Analysis (COA) documenting purity, identity, and impurity profiles are provided to guarantee traceability and compliance with customer specifications and relevant GMP guidelines.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture.
