Quality Control

Our Daidzein-D3-7-o-B-D-Glucopyranoside is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR, HPLC, and mass spectrometry, to confirm chemical identity, isotopic purity (D-enrichment), and chemical purity. Certificates of Analysis (COA) detailing batch-specific results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C in a dry, cool place. This product is hygroscopic (moisture-sensitive) and should be handled under anhydrous conditions to maintain stability and purity. Allow the sealed container to reach room temperature before opening to prevent condensation.
