Quality Control

Our 1,1'-[Methylenebis(6-Hydroxy-3,1-Phenylene)]Bis(1-Pentanone) is produced and handled under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing specifications such as assay (HPLC), related substances, and physical characteristics are provided and available upon request. We support compliance with cGMP and ISO standards for industrial and research applications.

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). Keep away from strong oxidizing agents, strong acids, and strong bases. Due to the phenolic hydroxyl groups, this material may be light-sensitive (store away from light) and should be handled under inert conditions if specified for high-purity grades.
