Quality Control

Our [2,2'-Dimethyl[1,1'-Biphenyl]-4,4'-Diyl]Diammonium Sulphate is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing to ensure identity, purity, and consistency, meeting the high standards required for fine chemical intermediates. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment and is available upon request.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
