Quality Control

We maintain stringent quality control protocols for all our fine chemical intermediates. Production adheres to ISO 9001 quality management principles, and batches are released only after passing comprehensive analytical testing. A detailed Certificate of Analysis (COA) is provided with each shipment, confirming identity, purity, and impurity profiles. For projects requiring specific regulatory support, we can discuss compliance with ICH Q7 guidelines and other relevant standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to minimize exposure to atmospheric moisture. For long-term storage, consider using desiccants.
