Quality Control

Our 3-Methyl-5-(1,1,3,3-Tetramethylbutyl)Pyrocatechol is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise specifications and consistent performance for industrial applications. Certificates of Analysis (COA) documenting all critical quality parameters are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its nature as an easily oxidized compound, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation of quality, especially after opening the original container. Keep away from strong oxidizing agents.
