Quality Control

Our β-Naphthyl Phosphate, Disodium Salt is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing including HPLC for purity, NMR for structural confirmation, and tests for residual solvents and moisture to ensure it meets high-purity standards for research and industrial use. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after use to prevent degradation from atmospheric moisture.
