Quality Control

Our 4-Aminopyridine-2-Sulfonic Acid is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC, NMR, and elemental analysis, to ensure identity, purity, and consistency. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment. We support compliance with REACH and other global regulatory frameworks.

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 tightly sealed after opening to prevent degradation from atmospheric moisture.
