Quality Control

Our 1,2,4-Butanetricarboxylic Acid is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and impurity profiles. A comprehensive Certificate of Analysis (COA) detailing results for assay, related substances, and physical parameters is provided with every shipment to guarantee traceability and batch-to-batch consistency.

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 tightly sealed after opening to prevent absorption of atmospheric moisture. Keep away from incompatible materials such as strong bases and oxidizing agents.
