Quality Control

Our Klion-D is produced under strict quality management systems to ensure batch-to-batch consistency and high purity. The product undergoes comprehensive analytical testing, including HPLC, GC, and NMR, to verify identity and potency. A Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee compliance with your specifications.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
