Quality Control

Our L(-)-Arabonic Acid-γ-Lactone is manufactured under a strict quality management system to ensure batch-to-batch consistency and high purity. We provide comprehensive analytical data, including HPLC purity, optical rotation, and residual solvent analysis. Certificates of Analysis (COA) detailing all specifications are available for every batch upon request, supporting compliance in regulated applications.

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 may affect product stability and performance.
