Quality Control

Our [As,(+)]-2,3-Dihydro-5,5',6,6',8,8'-Hexahydroxy-2,2'-Dimethyl[9,9'-Bi[4H-Naphtho[2,3-B]Pyran]]-4,4'-Dione is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing including chiral purity analysis (HPLC), structural confirmation (NMR, IR), and impurity profiling to ensure consistent high purity and optical integrity. Certificates of Analysis (COA) with detailed chromatographic data are provided for every shipment, supporting rigorous R&D and regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at a controlled room temperature (15-25°C) in a cool, dry, and well-ventilated place. Due to its sensitivity to oxidation, the container should be sealed immediately after use to minimize exposure to air.
