Quality Control

Our 1-Methyl-4-Isopropyl-1,4-Ethano-5-Cyclohexene-2,3-Dicarboxylic Acid Barium Salt is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure consistent purity, precise metal content, and low levels of critical impurities. Certificates of Analysis (COA) detailing assay, heavy metals, moisture content, and other relevant parameters are provided to guarantee compliance with your specific application requirements.

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 (moisture-sensitive) nature, the container must be kept sealed when not in use to prevent absorption of atmospheric moisture, which can affect product performance and flow characteristics.
