Quality Control

Our production of L-?Riburonic Acid derivative adheres to stringent in-house quality protocols to ensure batch-to-batch consistency and high purity. Each lot is supported by a comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles. We are committed to meeting the exacting standards required for research and cGMP manufacturing, with specifications available for various grades including Research, Technical, and Pharmaceutical Development grades.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from heat and incompatible materials.
