Quality Control

Our Dihydroalantolactone is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC, GC, and NMR, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided and available upon request 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 controlled room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to store the product under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from heat, sparks, and open flame.
