Quality Control

Our 5,5′-(Butane-1,4-Diyl)-Bis(Oxy)Diisophthalic Acid is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure high purity and consistency. Certificates of Analysis (COA) with detailed specifications from HPLC, NMR, and IR are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, store in a cool, dry place at a controlled room temperature (15-25°C). For long-term storage, consider using a desiccator or maintaining an inert atmosphere to prevent moisture absorption and potential degradation.
