Quality Control

Our Eserethole is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC, GC, and NMR, to confirm identity and purity. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting all critical quality parameters.

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 nature, the container must be kept tightly sealed to prevent moisture absorption, which may affect product stability.
