Quality Control

Our 4,4'-(1,6-Hexanediyl)Dioxydianiline is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets exacting industry standards. Certificates of Analysis (COA) detailing purity, moisture content, and other critical parameters are available upon request to support your quality assurance and regulatory compliance needs.

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). Keep away from heat, open flames, and incompatible materials such as strong oxidizing agents. Due to its light-sensitive nature, containers should be kept in opaque packaging or amber glass.
