Quality Control

Our 3,4,o-Isopropylidene-L-Arabinose is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and chiral integrity, to ensure it meets the high standards required for synthetic applications. Certificates of Analysis (COA) documenting identity, purity, and specific impurities are available upon request to support your regulatory and R&D needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect product stability and performance.
