Quality Control

Our 3,9-Dihydroxy-1,7-Dimethyl-2,6-Dibenzofurandicarboxylic Acid is produced under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise customer specifications and industry standards. Comprehensive Certificates of Analysis (COA) documenting all critical quality attributes are available upon request.

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 degradation from atmospheric moisture.
