Quality Control

Our 4,4'-Bi[2,3,6-Trimethylphenol] is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise customer specifications. Certificates of Analysis (COA) documenting all critical parameters are available upon request, supporting compliance in regulated applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to store the material under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep away from strong oxidizing agents.
