Quality Control

Our L-Erythro-Penturonic Acid, 4-Deoxy-3-o-Methyl-, γ-Lactone (9Ci) is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity verification by HPLC, to ensure it meets the exacting standards required for pharmaceutical R&D and fine chemical synthesis. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment.

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 tightly sealed in a dry environment to prevent product degradation.
