Quality Control

Our (4-Amino-3-Methyl-Phenyl)-Bis(4-Aminophenyl)Methanol is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets the highest standards of purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with every shipment to guarantee traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic and easily oxidized nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen) after opening to prevent moisture absorption and degradation.
