Quality Control

Our 3,6-Dimethylcyclohexane-1,2-Dicarboxylic Anhydride is produced under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets precise chemical and physical specifications. Certificates of Analysis (COA) documenting purity, identity, and key parameters are available upon request, providing full traceability and compliance assurance for your supply chain.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality. Keep away from incompatible materials such as strong bases, amines, and alcohols.
