Quality Control

Our 2-Methyl-1,4-Naphthylene Bis(Hydrogen Sulphate) is produced under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay, impurity profile, and moisture content. Our quality commitment supports applications requiring high-purity intermediates, including those under GMP guidelines for pharmaceutical development.

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 tightly sealed after opening to prevent degradation from atmospheric moisture. Keep away from strong bases and oxidizing agents.
