Quality Control

Our Isomhpg is manufactured under a strict quality management system to ensure batch-to-batch consistency and high purity. Quality is verified through comprehensive analytical techniques including HPLC, GC, and NMR. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment. Production can adhere to cGMP guidelines for pharmaceutical applications upon request.

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 after opening to prevent moisture absorption, which can affect stability and performance. Keep away from incompatible materials.
