Quality Control

Our Citric Acid Anhydride Acetate is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR, to ensure it meets precise customer specifications. A comprehensive Certificate of Analysis (COA) detailing purity, impurity profile, and physical characteristics is provided with every shipment to guarantee traceability and compliance.

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 to prevent degradation from atmospheric moisture. Keep away from incompatible materials such as strong bases, oxidizing agents, and amines.
