Quality Control

Our Calcium Levulinate Dihydrate is manufactured under a strict quality management system. Each batch is tested to ensure it meets high-purity standards suitable for pharmaceutical and food-grade applications. Certificates of Analysis (COA) documenting identity, assay, impurity profiles, and other critical parameters are provided with every shipment. We can support compliance with relevant standards such as USP, FCC, and EP upon request.

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 minimize exposure to atmospheric moisture. Keep away from incompatible materials.
