Quality Control

Our Hqda is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including identification, assay, and impurity profiling via techniques such as HPLC, NMR, and IR spectroscopy. Certificates of Analysis (COA) documenting full specifications are provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to handle under an inert atmosphere for long-term storage or when opening new containers. Keep away from incompatible materials.
