Quality Control

Our Lanthanum(III) 2-Butenedioate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure high purity, consistent composition, and batch-to-batch reliability. Standard testing includes assay (lanthanum content), identification, and control of specific impurities. A comprehensive Certificate of Analysis (COA) documenting all test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area. Due to its hygroscopic nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric moisture. Recommended long-term storage temperature is 15-25°C.
