Quality Control

Our Enheptin is produced under strict quality management systems to ensure batch-to-batch consistency and high purity suitable for pharmaceutical applications. Each lot undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation. A Certificate of Analysis (COA) detailing all test results is provided with every shipment. We can support compliance with cGMP and other relevant regulatory standards as required.

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 nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect stability and handling properties.
