Quality Control

Our Arabinaric Acid is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity, chiral analysis, and residual solvent screening, to ensure it meets the high standards required for research and industrial applications. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming identity, purity, and conformance to agreed specifications.

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 each use to prevent moisture absorption, which can affect stability and handling properties.
