Quality Control

Our Guayulin C is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for purity assessment and spectroscopic methods (NMR, MS) for structural confirmation. A Certificate of Analysis (COA) detailing all specifications and test results is provided with every shipment. We adhere to cGMP principles where applicable to support its use in regulated research environments.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C or as indicated on the label or COA. This product is hygroscopic (moisture-sensitive); ensure the container is sealed tightly after each use to minimize exposure to atmospheric humidity. For long-term storage, consider storing under an inert atmosphere.
