Quality Control

Our 1-Phenanthrenesulfonic Acid is produced and handled under a strict quality management system. Each batch undergoes comprehensive analytical testing, including identity confirmation, purity assay, and impurity profiling, to ensure it meets exacting standards for research and industrial use. A Certificate of Analysis (COA) detailing all test results 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 (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture. Keep away from strong bases and incompatible materials.
