Quality Control

Our Glutaric Anhydride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets high-purity standards suitable for industrial and research applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles 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. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation by atmospheric moisture. Recommended long-term storage temperature is between 2°C and 8°C.
