Quality Control

Our Humulinic Acid is produced and tested under a rigorous quality management system. Each batch is analyzed to ensure it meets high-purity standards suitable for research and industrial use. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to guarantee traceability and batch-to-batch consistency.

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 light-sensitive and easily oxidized nature, it is recommended to store the material under an inert atmosphere for long-term preservation and to minimize exposure to air upon opening.
